Hello,
I would like to know if its is possible to subtitute elements in a matrix by conditions. Imagine a matrix in where there are number between 1-100, i want to set all value that are under 30 to 0, all between 30 and 75 to 1 and between 75 and 100 to 2, how do i do it? is that even possible? thank you

Let A be your matrix.
B = A ;
B(B<30) = 0 ; % replace < 30 to 0
B(B>=30 && B<75) = 1 ;
