Hello Guys I have really rather simple question: I want to set an array value into the follow [1, 3, 1, 7;1, 3, 1, 7;1, 3, 1, 7] and I used the following command a(1:3,1:3)=[1 3 1 7] But it is not working. Any clues ? Thank you.

Another:
A = repmat([1,3,1,7],3,1) % change the 3 to 5 to get 5 rows, etc...

r=[1 3 1 7]
a=[r;r;r]
or
r=[1 3 1 7]
b=ones(4,1)*r
b=b(1:3,:)
or
r=[1 3 1 7]
repmat(r,3,1)

Use the repmat function to replicate rows
