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];
plot(w)

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 ;
