put a mall matrix in a big matrix

Helll everybody,
A = zeros(672,34953);
I want to put a quadratic matrix (672,672) B, beginning at this spot (1,5377)
anybody has any idea how can i implement it quickly and efficiently ?
Thanks

A( 1: 1 + size(B,1)-1, 5377 : 5377 + size(B, 2) - 1 ) = B;

You are welcome.
By the way: you may want to mark answers as 'accepted answer', if they helped you solve your problem.
is there a quick efficient solution as well for 2 similar little matrices ? like in spot (1,5377) and (1, 25347) ?
Very similar to the answer I gave you before. You will only have to adapt the spot indices.
so 2 lines for 2 matrices ?
Why is that a problem? If you really have something specific you are trying to solve, then ask a direct question.
