Sorry, I meant to say that in Octave which() returns an empty string.

I should add that when called as a function which() returns an empty string for each of the examples provided, while Matlab returns the path string for the first and last example.

For a user-defined class 'myclass', which() has different behavior on Octave and Matlab. For example, given the attached file, placed in a @myclass directory on the path, I get the following:


>> which myclass
/Users/ray/test/@myclass/myclass.m  % myclass constructor

>> which @myclass
'@myclass' not found.

>> which @myclass/myclass
/Users/ray/test/@myclass/myclass.m  % myclass constructor


> which myclass
'myclass' is a built-in function

> which @myclass

> which @myclass/myclass
'@myclass/myclass' is a built-in function
