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.
