Read two matrices from CSV file then add them together

Hi I read two matrices A=B=20*100 from CSV file then I try to add them together and I failed I used C=A+B and I use loop but it is not working I want to sum the same cell together i.e C(1,1)=A(1,1)+B(1,1), C(1,2)=A(1,2)+B(1,2) and so on. The problem I got is all the cell in matrix C is equal to (2)

any idea

Regards

You do not need to use loop for matrix sum.

Please explain more about your matrices, such as type, value, size.

Hi,

 Thank you for your reply
Size A=20*100
size of B=20*100
values of A and B (numbers)

You can read the matrices using dlmread. After you've done this, what is the size of A and B? It must be the same. Basically, it is as simple as

A = dlmread('yourfile1.csv');
B = dlmread('yourfile2.csv');
C = A + B;

If all values in C are 2, what are the values in A and B?
