70 * @brief A standard container giving FILO behavior.

71 *
│ │ │ +
72 * @ingroup sequences
│ │ │ +
73 *
│ │ │ +
74 * @tparam _Tp Type of element.
│ │ │ +
75 * @tparam _Sequence Type of underlying sequence, defaults to deque<_Tp>.
│ │ │ +
76 *
│ │ │ +
77 * Meets many of the requirements of a
│ │ │ +
78 * <a href="tables.html#65">container</a>,
│ │ │ +
79 * but does not define anything to do with iterators. Very few of the
│ │ │ +
80 * other standard container interfaces are defined.
│ │ │ +
81 *
│ │ │ +
82 * This is not a true container, but an @e adaptor. It holds
│ │ │ +
83 * another container, and provides a wrapper interface to that
│ │ │ +
84 * container. The wrapper is what enforces strict
│ │ │ +
85 * first-in-last-out %stack behavior.
│ │ │ +
86 *
│ │ │ +
87 * The second template parameter defines the type of the underlying
│ │ │ +
88 * sequence/container. It defaults to std::deque, but it can be
│ │ │ +
89 * any type that supports @c back, @c push_back, and @c pop_back,
│ │ │ +
90 * such as std::list, std::vector, or an appropriate user-defined
│ │ │ +
91 * type.
│ │ │ +
92 *
│ │ │ +
93 * Members not found in @a normal containers are @c container_type,
│ │ │ +
94 * which is a typedef for the second Sequence parameter, and @c
│ │ │ +
95 * push, @c pop, and @c top, which are standard %stack/FILO
│ │ │ +
96 * operations.

67 * @section mathsf_desc Mathematical Special Functions
│ │ │ +
68 *
│ │ │ +
69 * A collection of advanced mathematical special functions,
│ │ │ +
70 * defined by ISO/IEC IS 29124 and then added to ISO C++ 2017.
│ │ │ +
71 *
│ │ │ +
72 *
│ │ │ +
73 * @subsection mathsf_intro Introduction and History
│ │ │ +
74 * The first significant library upgrade on the road to C++2011,
│ │ │ +
75 * <a href="http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1836.pdf">
│ │ │ +
76 * TR1</a>, included a set of 23 mathematical functions that significantly
│ │ │ +
77 * extended the standard transcendental functions inherited from C and declared
│ │ │ +
78 * in @<cmath@>.
│ │ │ +
79 *
│ │ │ +
80 * Although most components from TR1 were eventually adopted for C++11 these
│ │ │ +
81 * math functions were left behind out of concern for implementability.
│ │ │ +
82 * The math functions were published as a separate international standard
│ │ │ +
83 * <a href="http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2010/n3060.pdf">
│ │ │ +
84 * IS 29124 - Extensions to the C++ Library to Support Mathematical Special
│ │ │ +
85 * Functions</a>.
│ │ │ +
86 *
│ │ │ +
87 * For C++17 these functions were incorporated into the main standard.
│ │ │ +
88 *
│ │ │ +
89 * @subsection mathsf_contents Contents
│ │ │ +

113 * The hypergeometric functions were stricken from the TR29124 and C++17
│ │ │ +
114 * versions of this math library because of implementation concerns.
│ │ │ +
115 * However, since they were in the TR1 version and since they are popular
│ │ │ +
116 * we kept them as an extension in namespace @c __gnu_cxx:
│ │ │ +
117 * - @ref __gnu_cxx::conf_hyperg "conf_hyperg - Confluent hypergeometric functions"
│ │ │ +
118 * - @ref __gnu_cxx::hyperg "hyperg - Hypergeometric functions"

119 *
│ │ │ +
120 * <!-- @subsection mathsf_general General Features -->
│ │ │ +
121 *
│ │ │ +
122 * @subsection mathsf_promotion Argument Promotion
│ │ │ +
123 * The arguments suppled to the non-suffixed functions will be promoted
│ │ │ +
124 * according to the following rules:
│ │ │ +
125 * 1. If any argument intended to be floating point is given an integral value
│ │ │ +
126 * That integral value is promoted to double.
│ │ │ +
127 * 2. All floating point arguments are promoted up to the largest floating
│ │ │ +
128 * point precision among them.
│ │ │ +
129 *
│ │ │ +
130 * @subsection mathsf_NaN NaN Arguments
│ │ │ +
131 * If any of the floating point arguments supplied to these functions is
│ │ │ +
132 * invalid or NaN (std::numeric_limits<Tp>::quiet_NaN),
│ │ │ +
133 * the value NaN is returned.
│ │ │ +
134 *
│ │ │ +
135 * @subsection mathsf_impl Implementation
│ │ │ +
136 *
│ │ │ +
137 * We strive to implement the underlying math with type generic algorithms
│ │ │ +
138 * to the greatest extent possible. In practice, the functions are thin
│ │ │ +
139 * wrappers that dispatch to function templates. Type dependence is
│ │ │ +
140 * controlled with std::numeric_limits and functions thereof.
│ │ │ +
141 *
│ │ │ +
142 * We don't promote @c float to @c double or @c double to <tt>long double</tt>
│ │ │ +
143 * reflexively. The goal is for @c float functions to operate more quickly,
│ │ │ +
144 * at the cost of @c float accuracy and possibly a smaller domain of validity.
│ │ │ +
145 * Similaryly, <tt>long double</tt> should give you more dynamic range
│ │ │ +
146 * and slightly more pecision than @c double on many systems.
│ │ │ +
147 *
│ │ │ +
148 * @subsection mathsf_testing Testing
│ │ │ +
149 *
│ │ │ +
150 * These functions have been tested against equivalent implementations
│ │ │ +
151 * from the <a href="http://www.gnu.org/software/gsl">
│ │ │ +
152 * Gnu Scientific Library, GSL</a> and
│ │ │ +
153 * <a href="http://www.boost.org/doc/libs/1_60_0/libs/math/doc/html/index.html">Boost</a>
│ │ │ +
154 * and the ratio
│ │ │ +
155 * @f[
│ │ │ +
156 * \frac{|f - f_{test}|}{|f_{test}|}
│ │ │ +
157 * @f]
│ │ │ +
158 * is generally found to be within 10<sup>-15</sup> for 64-bit double on
│ │ │ +
159 * linux-x86_64 systems over most of the ranges of validity.
│ │ │ +
160 *
│ │ │ +
161 * @todo Provide accuracy comparisons on a per-function basis for a small
│ │ │ +
162 * number of targets.

The goal is for @c float functions to operate more quickly, │ │ │ │ +144 * at the cost of @c float accuracy and possibly a smaller domain of │ │ │ │ +validity. │ │ │ │ +145 * Similaryly, long double should give you more dynamic range │ │ │ │ +146 * and slightly more pecision than @c double on many systems. │ │ │ │ +147 * │ │ │ │ +148 * @subsection mathsf_testing Testing │ │ │ │ +149 * │ │ │ │ +150 * These functions have been tested against equivalent implementations │ │ │ │ +151 * from the │ │ │ │ +152 * Gnu Scientific Library, GSL and │ │ │ │ +153 * Boost │ │ │ │ +154 * and the ratio │ │ │ │ +155 * @f[ │ │ │ │ +156 * \frac{|f - f_{test}|}{|f_{test}|} │ │ │ │ +157 * @f] │ │ │ │ +158 * is generally found to be within 10-15 for 64-bit double on │ │ │ │ +159 * linux-x86_64 systems over most of the ranges of validity. │ │ │ │ +160 * │ │ │ │ +161 * @todo Provide accuracy comparisons on a per-function basis for a small │ │ │ │ +162 * number of targets. │ │ │ │ +163 * │ │ │ │ +164 * @subsection mathsf_bibliography General Bibliography │ │ │ │ +165 * │ │ │ │ +166 * @see Abramowitz and Stegun: Handbook of Mathematical Functions, │ │ │ │ +167 * with Formulas, Graphs, and Mathematical Tables │ │ │ │ +168 * Edited by Milton Abramowitz and Irene A.

82 * This is not a true container, but an @e adaptor. It holds another

84 * wrapper is what enforces strict first-in-first-out %queue behavior.

85 *

86 * The second template parameter defines the type of the underlying
│ │ │ +
87 * sequence/container. It defaults to std::deque, but it can be any type
│ │ │ +
88 * that supports @c front, @c back, @c push_back, and @c pop_front,
│ │ │ +
89 * such as std::list or an appropriate user-defined type.
│ │ │ +
90 *
│ │ │ +
91 * Members not found in @a normal containers are @c container_type,
│ │ │ +
92 * which is a typedef for the second Sequence parameter, and @c push and

93 * @c pop, which are standard %queue/FIFO operations.

457 * @brief A standard container automatically sorting its contents.
│ │ │ +
458 *
│ │ │ +
459 * @ingroup sequences
│ │ │ +
460 *
│ │ │ +
461 * @tparam _Tp Type of element.
│ │ │ +
462 * @tparam _Sequence Type of underlying sequence, defaults to vector<_Tp>.
│ │ │ +
463 * @tparam _Compare Comparison function object type, defaults to
│ │ │ +
464 * less<_Sequence::value_type>.
│ │ │ +
465 *
│ │ │ +
466 * This is not a true container, but an @e adaptor. It holds
│ │ │ +
467 * another container, and provides a wrapper interface to that
│ │ │ +
468 * container. The wrapper is what enforces priority-based sorting
│ │ │ +
469 * and %queue behavior. Very few of the standard container/sequence
│ │ │ +
470 * interface requirements are met (e.g., iterators).
│ │ │ +
471 *
│ │ │ +
472 * The second template parameter defines the type of the underlying
│ │ │ +
473 * sequence/container. It defaults to std::vector, but it can be
│ │ │ +
474 * any type that supports @c front(), @c push_back, @c pop_back,
│ │ │ +
475 * and random-access iterators, such as std::deque or an
│ │ │ +
476 * appropriate user-defined type.
│ │ │ +
477 *
│ │ │ +
478 * The third template parameter supplies the means of making
│ │ │ +
479 * priority comparisons. It defaults to @c less<value_type> but
│ │ │ +
480 * can be anything defining a strict weak ordering.
│ │ │ +
481 *
│ │ │ +
482 * Members not found in @a normal containers are @c container_type,
│ │ │ +
483 * which is a typedef for the second Sequence parameter, and @c
│ │ │ +
484 * push, @c pop, and @c top, which are standard %queue operations.
│ │ │ +
485 *
│ │ │ +
486 * @note No equality/comparison operators are provided for
│ │ │ +
487 * %priority_queue.
│ │ │ +
488 *
│ │ │ +
489 * @note Sorting of the elements takes place as they are added to,
│ │ │ +
490 * and removed from, the %priority_queue using the
│ │ │ +
491 * %priority_queue's member functions. If you access the elements
│ │ │ +
492 * by other means, and change their data such that the sorting
│ │ │ +
493 * order would be different, the %priority_queue will not re-sort
│ │ │ +
494 * the elements for you. (How could it know to do so?)

It defaults to @c less but │ │ │ │ +480 * can be anything defining a strict weak ordering. │ │ │ │ +481 * │ │ │ │ +482 * Members not found in @a normal containers are @c container_type, │ │ │ │ +483 * which is a typedef for the second Sequence parameter, and @c │ │ │ │ +484 * push, @c pop, and @c top, which are standard %queue operations. │ │ │ │ +485 * │ │ │ │ +486 * @note No equality/comparison operators are provided for │ │ │ │ +487 * %priority_queue. │ │ │ │ +488 * │ │ │ │ +489 * @note Sorting of the elements takes place as they are added to, │ │ │ │ +490 * and removed from, the %priority_queue using the │ │ │ │ +491 * %priority_queue's member functions.
