11.11 Organization of Functions Distributed with Octave

Many of Octave's standard functions are distributed as function files. They are loosely organized by topic, in subdirectories of ‘octave-home/lib/octave/version/m’, to make it easier to find them.

The following is a list of all the function file subdirectories, and the types of functions you will find there.

audio

Functions for playing and recording sounds.

control

Functions for design and simulation of automatic control systems.

elfun

Elementary functions.

finance

Functions for computing interest payments, investment values, and rates of return.

general

Miscellaneous matrix manipulations, like flipud, rot90, and triu, as well as other basic functions, like ismatrix, nargchk, etc.

image

Image processing tools. These functions require the X Window System.

io

Input-output functions.

linear-algebra

Functions for linear algebra.

miscellaneous

Functions that don't really belong anywhere else.

optimization

Minimization of functions.

path

Functions to manage the directory path Octave uses to find functions.

pkg

Install external packages of functions in Octave.

plot

Functions for displaying and printing two- and three-dimensional graphs.

polynomial

Functions for manipulating polynomials.

set

Functions for creating and manipulating sets of unique values.

signal

Functions for signal processing applications.

sparse

Functions for handling sparse matrices.

specfun

Special functions.

special-matrix

Functions that create special matrix forms.

startup

Octave's system-wide startup file.

statistics

Statistical functions.

strings

Miscellaneous string-handling functions.

testfun

Perform unit tests on other functions.

time

Functions related to time keeping.
