If you just have values in a vector, then

s(s<0) = [];

will remove them (leaving you with a vector of shorter length), or

s(s<0) = 0;

will set the negative values to zero, or

s(s<0) = NaN;

will set them to NaN.

If you mean something else, please provide more detail.

Can you just say signal<0 for getting it negative values? Because I had an error for doing that while writing a condition for if statement
