what is the most efficient way to set several matrix values to zero ?
I want to know which is the most efficient way to set a lot of matrix values to zero. I currently have a 90x90x7613 matrix with several numbers inside that should be set to zero (note: not all of them). The values that should be set two zero are stored inside a vector. My current approach is this: for i=1:length(vec) matrix(matrix==vec(i))=0; end Is there a more efficient way to do it ?

matrix(ismember(matrix, vec)) = 0
