Hi all,
I have a 3x1 column vector and I want to build a column vector of size (n).
Example:-
Assume
a=[1+j*0 ; -0.5000 -j*0.8660 ; -0.5000 + j*0.8660]

How can I build a column vector say (b) of size (n=12) form vector (a)?
vector b should look like:
b=[1+j*0
-0.5000 -j*0.8660
-0.5000 + j*0.8660
1+j*0
-0.5000 -j*0.8660
-0.5000 + j*0.8660
1+j*0
-0.5000 -j*0.8660
-0.5000 + j*0.8660
1+j*0
-0.5000 -j*0.8660
-0.5000 + j*0.8660];

See the help for the REPMAT function.

You need matlab's 'repmat'. Check it out.
