I'm trying to select certain points from a very large matrix using Matlab that fall in a value range and make the rest of the values zeroed in that matrix. The matrix is about 500x500 and I only want values between 9 and 10 to show and everything else zeroed. Please let me know if this is possible/ if you can help? Thanks!

x = [9,10,3,2,6;3,1,7,8,10];
x =
9 10 3 2 6
3 1 7 8 10
x(x<9 | x>10) = 0;
x =
9 10 0 0 0
0 0 0 0 10

If A is your matrix
A( A<9 | A>10)=0 ;
