MATLAB: How to add a matrix to a specfic place in bigger matrix

Question

Hello,

I have a big matrix: xt=zeros(6,6);

I want to add this matrix t=[1 1 ; -1 1];

So that xt becomes: xt =

1 1 0 0 0 0

-1 1 0 0 0 0

0 0 1 1 0 0

0 0 -1 1 0 0

0 0 0 0 1 1

0 0 0 0 -1 1

I want to generalize it for any size of xt but the same size of t.

Thanks in advance!

Answer 1

xt = xt + kron( speye(size(xt)/2), t)
