want to use a 'for' loop to swich between variables, like varname_1+n

I'm using a syntax to creat variables, in the next step I want to use the variables one by an other in a 'for' loop.

syntax to creat the variables: like A_1, A_2, A_3, ...

for f=1:1:18
a_LLK{f} = 'a_LLK_';

end

varnamelist1 = genvarname(a_LLK);

for l=1:1:18

      eval([genvarname(['a_LLK_' num2str(l)]) '= ...']);
     end

now I want to put the values of the createt variables in a Matrix.

for m=1:1:18

    B_LLK(:,m) = a_LLK_ *'m'*
  end

so that it will be count:

B_LLK(:,1) = a_LLK_1

B_LLK(:,2) = a_LLK_2

B_LLK(:,3) = a_LLK_3

. . .

thanks for help

Why create variables when you can just use a cell or a structure array?

[Simon Simon]

thats just a piec of the function usualy a_LLK_n are fft's in form of matrices. And I will take the inverse of the fft and put the results in B_LLK. Just try to write compact and short;)

@Simon Simon: Don't create the variables dynamically like this in the first place. Bad programming practices like this should be avoided. Use an N-D array, a cell array or a structure instead.

Beginners often think that it is a great idea to put meta-information is a variable name (e.g. consecutive numbers or test conditions), but really this is programmatically a poor idea: it prevents variable tracking and code checking tools from working, is slow and very buggy.
