mathematics - Module

Description

The mathematics module contains functions that perform a variety of mathematical operations. These functions can be grouped into the following catagories.

statistics: median, moments and the like
FFT: Fast Fourier Transforms and related functions
polynomials: Evaluation and fitting of polynomials
interpolation: One-dimensional interpolation using various functions
sinusoids: Fitting sinusoids to data
gaussians: Evaluate 1 and 2-D Gaussians, fit 1-D Gaussians
random numbers: Generate random numbers from a variety of distributions
matrix: Matrix and linear algebra operations
least squares: Least-squares inversion of simultaneous equations

This module does not duplicate functions that are built-in to Glish itself e.g.,, sin(). See the Glish Users Manual for a description of these functions.
