Math::MatrixDecomposition::Util - utility functions
use Math::MatrixDecomposition::Util qw(:all);
This module contains a colorful collection of utility functions. Nothing is exported by default.
epsReturn the machine precision.
mod (num, den)Return the remainder of a division. Any argument can be either an integral number or a floating-point number.
min (a, b)Return the minimum value of the two arguments.
max (a, b)Return the maximum value of the two arguments.
sign (a, b)Return the value of a with the sign of b.
If the second argument b is less than zero, the return value is a non-positive number. Otherwise, the return value is a non-negative number.
hypot (a, b)Return the length of the hypotenuse of a right triangle. This is equal to the distance of a point to the origin in a two-dimensional Cartesian coordinate system.
cdiv (a_re, a_im, b_re, b_im)Return the real part and imaginary part of the division of two complex numbers.
