Adding two different size matrices

Hi all

I have a one matrice whos size is 100x50 let say

A=ones(100,50)

and I want to add it with its transpose

B=A+A';

but I am getting error of matrix dimensions.

Any help is appreciated..........

You can't add matrices of different dimensions.

The transpose of A has dimension (50x100)

Think of it:

A =
[1 2
 3 4
 5 6];

B = 
[1 3 5
 2 4 6];

What would you want A+B to be?

A=ones(100,50);

A2 = zeros(max(A));
A2(1:numel(A)) = A;
B = A2 + A2';
