Is there any built-in function in matlab that takes all the negative values equal to zero? or round off negative values to zero? Regards

% Random input
A = randn(10,1);
% Index negative values
idx = A < 0;
% Substitute them with zero
A(idx) = 0;

A = max(A,0);
But cross-check whether this gives you the behaviour you want for NaN.
