matrix manipulation - replacing partial matrix subsets in main matrix ???
显示 更早的评论
I have two matrices : one is NxM and other is nxm (N>n, M>m).
I would like to insert nxm matrix at location starting at (x,y) by replacing existing subset.
example)
initial NxM
= 1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
nxm
= 2 2
2 2
(x,y) = (3,2)
final NxM
= 1 1 1 1 1
1 1 2 2 1
1 1 2 2 1
what is a way to do this using matlab?
thanks,

You can use colon indexing:
% Create the two matrices in your example
A = ones(3, 5);
B = 2 * ones(2, 2);
% Use indexing to assign B to a sub-array of A
A(2:3, 3:4) = B;
