Count number of values in matrix within given range

Question

I have matrix

A=[2 3 4 5 6 7;
   7 6 5 4 3 2]

I want to count how many number of elements have a value greater than 3 and less than 6.

Answer 1

You could use matlab for-loop and cycle through the values on your own. Pros is that any function can be specified (>2 & <5 ; >3 & <6; etc.), cons is that it's kind of heavy approach. Here's approximate code:

count = 0;
for i=1:length(A)
  element = A(i);
  if (element > 2 && element < 5) 
    count = count + 1;
  end
end
