Hi, suppose I have a matrix A as follows:
A =
1 2 3
3 3 6
4 6 8
4 7 7
I need to find the number of values of matrix A having value less than 6.
How to do this?
Thanks in advance

>> sum(A(A<6))
ans =

Your original question is phrased wrong though for the answer you wanted. Should be 'sum of values of matrix A'

RoJo is correct. Your original question asked for the *number* of values, and that is what I answered. RoJo's code is good if you want the total of those values.
