Hi,
My problem is I have two vectors,
one called 'Ua' of size (253,1)
and the other is called just 'vector' and is currently filled with zeros and is of size (4048,1).
What I want to do is fill rows 1:16 of 'vector' with Ua(1,1), fill rows 17:32 of 'vector' with Ua(2,1) etc. all the way up to filling rows 4032:4048 of vector with Ua(253,1).
What Ive tried to do, and does not work, is a really simple for loop as follows:
for i=1:253 vector(1:1:16:4048,1)=Ua(i,1); end
Obvioulsy this does not work and I'm struggling to figure out how to do this quite simple problem.
Can anyone offer any solutions?
Thanks
R

vector = repmat(Ua', [16, 1]);
vector = vector(:);
