Hi all,
How to replace the elements of a matrix with another matrices in one go with just a command?
for example: A = zeros(4,16) I want to replace the rows of A with the following matrices:
b=[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]
c=[2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2]
d=[3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3]
e=[4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4]
Thanks for your help.
Best wishes, S:-)

Try this:
A = [b;c;d;e]

Thanks for your quick reply Azzi. But matrices b to e are just examples here, and in my case they do not have such a simple elements. Thanks anyway:)
