This is an extremely bad idea. Warnings are the best friend of programmers. Do not switch them off.

Please post the complete error message. Then we do not have to guess, here the error occurs.

[Cris LaPierre]

You have a variable that is an mxnx1 array, and your code is telling MATLAB to index the 3rd dimension with a value >1.

theta1 = rand(3,2,1);
% Works
theta1(1,2,1)

ans = 0.7282

ans = 0.7707

ans = 0.7707

% Doesn't work
theta1(1,2,3)
