Hi
I am having problems in using the ismember function, so I want to replace ismember and I need help in replacing the function.
Below is example code
INData = [

The ismember function is doing exactly what you told it to do! What’s the problem?

An alternative approach
dMark = [7 13 30];
s_data = false(1, size(INData, 1));
s_data(dMark) = 1;
