How do I give order or number for "a" with ijk in the following code ? Please help me

for example :

a_ 111= 2

a_112=4

a_234=48

and so on

In other words, how do I show the " a" rank? and how is "a" data recorded in order to be called again?

What you are trying to do is not recommended in MATLAB since dynamically creating variables is not useful. You have several other options about creating variables. I suggest you to read the following tutorial:

https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval

For your problem, following code should do it:

for i=1:3
    for j=1:4
        for k=1:5
            eval(sprintf('a_%d%d%d=2*%d*%d*%d',i,j,k,i,j,k));
        end
    end
end

Please read the tutorial in order to understand what I meant.
