[manpage_begin math n 1.2.6] [keywords math] [keywords statistics] [comment {-*- tcl -*- doctools manpage}] [moddesc {Tcl Math Library}] [titledesc {Tcl Math Library}] [category Mathematics] [require Tcl "8.5 9"] [require math [opt 1.2.6]] [description] [para] The [package math] package provides utility math functions. [para] Besides a set of basic commands, available via the package [emph math], there are more specialised packages: [list_begin itemized] [item] [package math::bigfloat] - Arbitrary-precision floating-point arithmetic [item] [package math::bignum] - Arbitrary-precision integer arithmetic [item] [package math::calculus::romberg] - Robust integration methods for functions of one variable, using Romberg integration [item] [package math::calculus] - Integration of functions, solving ordinary differential equations [item] [package math::combinatorics] - Procedures for various combinatorial functions (for instance the Gamma function and "k out of n") [item] [package math::complexnumbers] - Complex number arithmetic [item] [package math::constants] - A set of well-known mathematical constants, such as Pi, E, and the golden ratio [item] [package math::fourier] - Discrete Fourier transforms [item] [package math::fuzzy] - Fuzzy comparisons of floating-point numbers [item] [package math::geometry] - 2D geometrical computations [item] [package math::interpolate] - Various interpolation methods [item] [package math::linearalgebra] - Linear algebra package [item] [package math::optimize] - Optimization methods [item] [package math::polynomials] - Polynomial arithmetic (includes families of classical polynomials) [item] [package math::rationalfunctions] - Arithmetic of rational functions [item] [package math::roman] - Manipulation (including arithmetic) of Roman numerals [item] [package math::special] - Approximations of special functions from mathematical physics [item] [package math::statistics] - Statistical operations and tests [list_end] [section "BASIC COMMANDS"] [list_begin definitions] [call [cmd ::math::cov] [arg value] [arg value] [opt [arg {value ...}]]] Return the coefficient of variation expressed as percent of two or more numeric values. [call [cmd ::math::integrate] [arg {list of xy value pairs}]] Return the area under a "curve" defined by a set of x,y pairs and the error bound as a list. [call [cmd ::math::fibonacci] [arg n]] Return the [arg n]'th Fibonacci number. [call [cmd ::math::max] [arg value] [opt [arg {value ...}]]] Return the maximum of one or more numeric values. [call [cmd ::math::mean] [arg value] [opt [arg {value ...}]]] Return the mean, or "average" of one or more numeric values. [call [cmd ::math::min] [arg value] [opt [arg {value ...}]]] Return the minimum of one or more numeric values. [call [cmd ::math::product] [arg value] [opt [arg {value ...}]]] Return the product of one or more numeric values. [call [cmd ::math::random] [opt [arg value1]] [opt [arg value2]]] Return a random number. If no arguments are given, the number is a floating point value between 0 and 1. If one argument is given, the number is an integer value between 0 and [arg value1]. If two arguments are given, the number is an integer value between [arg value1] and [arg value2]. [call [cmd ::math::sigma] [arg value] [arg value] [opt [arg {value ...}]]] Return the sample standard deviation of two or more numeric values. [call [cmd ::math::stats] [arg value] [arg value] [opt [arg {value ...}]]] Return the mean, standard deviation, and coefficient of variation (as percent) as a list. [call [cmd ::math::sum] [arg value] [opt [arg {value ...}]]] Return the sum of one or more numeric values. [list_end] [vset CATEGORY math] [include ../common-text/feedback.inc] [manpage_end]
