num2str in loop

simon ott — Tue, 20 Jan 2009 00:22:01 -0500

hello
I want to assign the name of a variable based on loop iteration.

b = [3 4 ]

Iteration = 1: 2

['abc' num2str(Iteration)] = b(i)

End

But it does not work

Any hint ?

Yes, that wouldn't work. Have you tried using eval as follows?

eval(['abc' num2str(Iteration) '= b(i);'])

Wow, I have never seen so many of these in such a short period of time!

It is very much recommended that you do not do this. Use cell arrays instead.
