When you remove the element from the matrix, what remains in that location?

100X15

x=randi([25 30]),100,15);
y=randi([20 50]),100,5);
w=[x y];

If A is your array....

You can remove data using:

A(A>30) = [] ;
A(A<25) = [] ;

Or replace them with NaN's, if yu want same size.

A(A>30) = NaN ;
A(A<25) = NaN ;
