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.
