The error suggests your code either can't find a function you use (it is not in the current folder or on the MATLAB path), or you are trying to use a variable that does not exist.
a = seq
Unrecognized function or variable 'seq'.
Your function returns a variable seq, so I suspect in your case it is the 2nd issue causing the error. A quick glance shows that seq is created in if statements, so what is likely happening is that your condition is never true, so seq is never created.
if Test=='T'
seq(:,:,v) = ...
