Without seeing your code, it is not possible to determine the problem. If 'name of function' is a variable (character array), there should be no problem.
Example:
x = 'name of function';
What are you doing with it?

I cannot determine what ‘peak’ is with respect to length:
YValue(j) = time(Location)
value=YValue'
The problem is that it will return a (1x2) vector for the result of the size call.
So:
peak = 1:42;
v = 10:size(peak)-4
v =
1×0 empty double row vector
That will not work, since plot expects vector arguments, and ‘empty’ vectors do not fulfill that requirement.
