KEYWORDS
package require Tcl 8.2
package require math ?1.2.4?
The math package provides utility math functions.
Besides a set of basic commands, available via the package math,
there are more specialised packages:
-
math::bigfloat - Arbitrary-precision floating-point
arithmetic
-
math::bignum - Arbitrary-precision integer arithmetic
-
math::calculus::romberg - Robust integration methods for
functions of one variable, using Romberg integration
-
math::calculus - Integration of functions, solving ordinary
differential equations
-
math::combinatorics - Procedures for various combinatorial
functions (for instance the Gamma function and "k out of n")
-
math::complexnumbers - Complex number arithmetic
-
math::constants - A set of well-known mathematical
constants, such as Pi, E, and the golden ratio
-
math::fourier - Discrete Fourier transforms
-
math::fuzzy - Fuzzy comparisons of floating-point numbers
-
math::geometry - 2D geometrical computations
-
math::interpolate - Various interpolation methods
-
math::linearalgebra - Linear algebra package
-
math::optimize - Optimization methods
-
math::polynomials - Polynomial arithmetic (includes families
of classical polynomials)
-
math::rationalfunctions - Arithmetic of rational functions
-
math::roman - Manipulation (including arithmetic) of Roman
numerals
-
math::special - Approximations of special functions from
mathematical physics
-
math::statistics - Statistical operations and tests
- ::math::cov value value ?value ...?
-
Return the coefficient of variation expressed as percent of two or
more numeric values.
- ::math::integrate 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.
- ::math::fibonacci n
-
Return the n'th Fibonacci number.
- ::math::max value ?value ...?
-
Return the maximum of one or more numeric values.
- ::math::mean value ?value ...?
-
Return the mean, or "average" of one or more numeric values.
- ::math::min value ?value ...?
-
Return the minimum of one or more numeric values.
- ::math::product value ?value ...?
-
Return the product of one or more numeric values.
- ::math::random ?value1? ?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 value1. If two
arguments are given, the number is an integer value between
value1 and value2.
- ::math::sigma value value ?value ...?
-
Return the population standard deviation of two or more numeric
values.
- ::math::stats value value ?value ...?
-
Return the mean, standard deviation, and coefficient of variation (as
percent) as a list.
- ::math::sum value ?value ...?
-
Return the sum of one or more numeric values.
