The help text does not explain the input and output arguments at all. The user is left to guessing how many there are, what they are, and what their dimensions are.
Little vectorization is done. For example, the following code from the submission is pretty silly.
for i = 1:Rows
Basic(i) = i;
end
The variable Basic is not even preallocated.
To cite another example, one line contains the command or function,
reture;
which is not included in the submission and is not a function in basic MATLAB
