We have made a matrix with 7 rows and 18 columns with random elements between 10-100. From these we have solved that there are 21 elements with a value between 35 and 55.
Now we have to calculate the summation of these 21 elements. How do we do that?

Ran in:
yourMatrix=rand(7,18)*90+10;
s=sum(yourMatrix(yourMatrix>=35&yourMatrix<=55))
s = 1.3268e+03
