Replace values like (-999) in matrix to zero with one statement?!
显示 更早的评论
I am looking for replacing values (-999) in a matrix (m*3) to zero. I can do that using for/While loop but my program is going to be delayed to execute.
Anyone experience change a values to zero?
Thanks in advance!

Mohammed - try something like the following. If mtx is your matrix
% create a 5x5 matrix
mtx = [-999 1 2 3 4;
5 -999 6 7 8;
9 10 -999 11 12;
13 14 15 -999 16;
17 18 19 20 -999];
% set all elements that are -999 to zero
mtx(mtx==-999) = 0;
This works only if the value you wish to replace is an integer.
Try the above and see what happens!
