eliminating value out of range

I have two matrix.

A = rand(8,10);
B = rand(8,41);

range = 0.5345 (y+ direction and y- direction, range of elements of A);

i want to take all elements of B which fall in the range of matrix A 's elements. The elements of B which does not fall in the range should be NaN.

I assume the code snippet you provide is just to demonstrate the size of A and B and not exactly how you create A and B? Because "A = rand(8,10);" will not necessarily yield a range of 0.5345.

yes, you are right.

Declare a logical variable that states when values are in range

inRange = B >= min(A(:)) & B <= max(A(:));

Now assign to nan if outside that range, as you asked:

B(~inRange) = nan;

Or you can extract only those that are in range into a new variable:

BInRange = B(inRange);

Or you can delete those that are not in range, giving a shorter B than the original:

B(~inRange) = [];
