Hello, I want to extend a Matrix Periodicly. I mean this:
a = [1,2,3,4];
period = 4;
and this has to be the result:
a = [1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4]
How is it possible? What I dont want to do is to use some sort of loop.
Because they are very inefficient and slow and I want to realize full vectorization in my Program.
The wextend command wont work for me, because my program has to run in Octave.
