MATLAB: Adding two different size matrices

Question

Hi all

I have a one matrice whos size is 100×50 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……….

Answer 1

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?
