Details:


On matlab you can get the file containing a function in a namespace (i.e. in a
package directory) using 'which' like below. Here I've created a directory
'+example_pkg' and put the m-file 'example_pkg_fcn.m' in it. This is a valid
mfile, just prints 'hello' which can be run in both matlab and octave. I've
attached it.

Matlab returns the following:


>> which example_pkg.example_pkg_fcn
/home/rcrozier/Sync/work/mfiles/octave_tests/+example_pkg/example_pkg_fcn.m  %
static method or package function


on Octave, 'which' returns nothing


>> x = which ('example_pkg.example_pkg_fcn')
x =

>>


actually, if you try to do the exact same as in matlab you get a syntax
error:


>> which example_pkg.example_pkg_fcn
>> x = which example_pkg.example_pkg_fcn
parse error:

  syntax error

>>> x = which example_pkg.example_pkg_fcn
                        ^


Octave doesn't seem to treat it as a string, but that's for another bug report
I guess!

For completeness, using function syntax on matlab gives


>> x = which ('example_pkg.example_pkg_fcn')

x =

   
'/home/rcrozier/Sync/work/mfiles/octave_tests/+example_pkg/example_pkg_fcn.m'
