index must be positive integer or logical

I am getting the above mention error while running my code. Help me how to fix this. for your information "length of tua=61" or tua= -15:0.5:15

Attempted to access T(61,0); index must be a positive integer or logical.

Error in phatLoc (line 17) T(length(tau),end) = 0;

Error in messl>initIpd (line 276) tauPosInit = phatLoc(lr, tau, I, 0, vis);

Error in messl (line 126) [ipdParams itds] = initIpd(I, W, Nrep, tau, sr, lr, tauPosInit, pTauIInit, ...

Error in Main (line 68) [m,p] = messl(lr, tau, 2, 'vis', 1);

Note that...MATLAB indices are always positive integers.......the indices start from 1....you are trying to access a index with 0..this is not correct.

A = rand(10,1) ;   
A1 = A(1)   % this gives first element
A1 = A(0)   % this is wrong..throws error.
