Array indices must be positive integers

I keep getting the error that my array indices are wrong. This for loop is nested inside of another for loop and it is fine the first time. However the second time I get the error. I have tried different things but I just don't see my mistake anymore. Could you please help me?

***EDIT***: Found te error, used Ts twice as a variable!

The error is clear......your indices are either negative or zeros double. When you are indexing, the indices should be either logical class (0,1) or positive integers.

Example:

A = [1 5 pi 2*pi cosd(90)] ; 
A(1)   % No error 
A(-1)  % error, becuase index is negative 
A(0)  % error becuase index is zero 
idx = A > 1 ;  % logical 
A(idx)  % no error, as idx is logical. 

Int he same whay, use debuggig and check why the indices are neagtive.
