Good idea to write matlab code as the other language like c.

Mu on 16 Jan 2019

Maybe I just don't have the matlab skills for this problem, but maybe the test suite is broken which makes it impossible to solve:
%%mkdir @function_handle

goc3 on 17 Jan 2019

The test suite has been fixed. (The initial line is no longer commented out.)

Another problem in the test suite? The 2nd line in the test suite:
movefile submission/colon.m @function_handle
gives an error:
The function colon is a built-in MATLAB function. Please use a different function name.

Fixed.
