Rounding-off zero to negative

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

Answer 1

[Oleg Komarov]

% Random input

A = randn(10,1);

% Index negative values

idx = A < 0;

% Substitute them with zero

A(idx) = 0;

Answer 2

[Walter Roberson]

A = max(A,0);

But cross-check whether this gives you the behaviour you want for NaN.
