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;

quick answer, quick solution. Thanks a lot

You are welcome.

By the way: you may want to mark answers as 'accepted answer', if they helped you solve your problem.

[Michael]

is there a quick efficient solution as well for 2 similar little matrices ? like in spot (1,5377) and (1, 25347) ?

[Jan]

Very similar to the answer I gave you before. You will only have to adapt the spot indices.

[Michael]

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.
