how to change variable name in for loop

I am trying to do a problem for structural analysis, i got stuck in this part trying to make a for loop give me different variables, here's the example. Thanks in advance!!

for i=1:nel

        kl   =[J(1,i)    0       0    -J(1,i)     0      0
                0     J(3,i)  J(2,i)     0    -J(3,i)  J(2,i)
                0     J(2,i)  J(4,i)     0    -J(2,i)  J(5,i)
              -J(1,i)    0       0     J(1,i)     0       0
                0    -J(3,i) -J(2,i)     0    J(3,i)  -J(2,i) 
                0     J(2,i)  J(5,i)     0   -J(2,i)   J(4,i)]
end

I need a new "kl" each iteration, can anybody help me out, it's my first month using matlab.

What is the problem with the shown code? You need a new kl in each itereation and you get a new one. So what is your question? What is the connection to the title "change varaible name"?

A bold guess: Do you want to store the different matrices in a variable?

kl = zeros(6, 6, nel)
for i = 1:nel
   kl(:,:,i) =[J(1,i)    0       0    -J(1,i)     0      0; ...
              0     J(3,i)  J(2,i)     0    -J(3,i)  J(2,i); ...
              0     J(2,i)  J(4,i)     0    -J(2,i)  J(5,i); ...
            -J(1,i)    0       0     J(1,i)     0       0; ...
              0    -J(3,i) -J(2,i)     0    J(3,i)  -J(2,i); ...
              0     J(2,i)  J(5,i)     0   -J(2,i)   J(4,i)];
end

Or in a cell array:

kl = cell(1, nel);
for i = 1:nel
  kl{i} = ...

Alejandro's comment moved here:

Thanks a lot, the problem was the one you boldly guessed. My only remaining question would be if there's a way of naming the matrices kl1, kl2, kl3, kl4, kln instead of kl(:,:,1) etc?

[Oleg Komarov]

@Alejandro: absolutely avoid this programming practice. Keep the data in one place and if you need the meta info associated withe the name of the slice, then use structures or tables.

@Alejandro: Hiding an index in the name of a variable is a bad programming style.
