Wherever you found this code, you need to download the associated functions with it. (Which I also said on the other question you asked about this.)

This appears to refer to an old course ASEN 5007, 'Introduction to Finite Element Methods". The original code appears to have been written in Mathematica. I did not locate MATLAB equivalent code. Perhaps it was just expored from Mathematica by calling a Mathematica routine that translates to MATLAB.
