I think this should be split into two bug reports. Unless you think the scope issue is related to the feval issue?

Confirmed.  Changing to the "dev" release since the issue is still present there and it will need to be fixed there first.

It seems that the class name, which amounts to a scope operator, is ignored.  I tried this code

classdef test_feval_static_method_with_name_ls

    methods (Static)

        function x = ls ()

            x = 1;




and when executing

feval ('test_feval_static_method_with_name_ls.ls')

the actual function that gets executed is from ls.m.

It is perhaps a separate bug report, but I also came across this weird behavior while testing:

classdef test_feval_static_method_with_name_test

    methods (Static)

        function x = test ()

            x = 1;




octave:11> test_feval_static_method_with_name_test.test
ans = 1.0000e+000
octave:12> feval ('test_feval_static_method_with_name_test.test')
error: Invalid call to test.  Correct usage is:

 -- test NAME
 -- test NAME quiet|normal|verbose
 -- test ("NAME", "quiet|normal|verbose", FID)
 -- test ("NAME", "quiet|normal|verbose", FNAME)
 -- SUCCESS = test (...)
 -- [CODE, IDX] = test ("NAME", "grabdemo")
 -- test ([], "explain", FID)
 -- test ([], "explain", FNAME)

classdef test_feval_static_method

        function x = return_one ()

            x = 1;




octave:7> test_feval_static_method.return_one
ans = 1.0000e+000
octave:8> feval ('test_feval_static_method.return_one')
error: feval: function 'test_feval_static_method.return_one' not found
