== Missing Functions == | == Contribution == | ||
There are many ways to contribute to the development and maintenance of the signal processing package, including but not limited to testing, writing new test cases, reviewing and editing documentation, creating useful demos or examples of how to use the functions in the package, fixing bugs in existing functions, improving compatibility with Matlab, and writing completely new functions. | |||
=== Missing Tests === | |||
Octave functions can be written to include their own built-in self tests that work with the {{manual|test}} function, see [[Tests]]. | |||
Several functions in the signal package do not have exhaustive test suites or do not include any built-in self tests at all. This is a list of functions in the signal package that do not yet have any tests. | |||

=== Missing Functions === | |||
This is a list of functions that are not yet implemented in the Octave signal package. Patches for some of these functions are available on the patch tracker and are undergoing review. You could help us by implementing the missing functions and adding them to the patch tracker, or by helping us review the ones that are already there. This list is subject to change and may not be complete in any sense. However, it is a starting point when looking for missing functionality or for possible projects to work on. | This is a list of functions that are not yet implemented in the Octave signal package.
