Addition of two unequal matrices

I have two matrices of binary variables, e.g A = [1 0;1 1;0 1] and B = [1;0;1].My first question is how to add these matrices, and the other question is I want to apply this statement on the result: A + B <=1. Thanks

You can't add the two unequal dimension matrices (Basic Maths)

I know, but I want to add zeros to the the remaining position and add these two matrices.

add zeros to the the remaining position

Can you explain what you mean exactly?

Answer 1

[KSSV]

A = [1 0;1 1;0 1]
B = [1;0;1]

idx = A+B<=1

Answer 2

You cannot compute A+B. You can only compute the sum for each column:

A+B
ans =

     2     1
     1     1
     1     2
