八度音程中@的含义 forge function 参考

Question

I'm using some packages from from Octave Forge . In the API documentation some of the functions are prefixed with @<AnOtherName>/..

As Example:

@lti/c2d

What is the meaning of this prefix with @ and the additional name? What is the difference to "normal" functions?

Answer 1

lti is a class, @lti/c2d refers to the c2d method of the lti class.

In old-style class definitions, class methods for a class lti are M-files in a directory called @lti , so the c2d method would be defined in a file @lti/c2d.m .

New-style class definitions use a single classdef file to define all methods, but it is still possible to override functions for a specific class or type by creating M-files in a directory @<class> . For example, you can create an M-file @double/foo.m to create a function foo that exists only on inputs of type double .
