How to get the value assigned to a variable inside a variable in MATLAB?

A1, A2,... are assigned to t. And A1, A2, A3,.... are further have values as assigned in below for loop. Now when I am printing print(t(1,:)), I want the answer 2, but I am getting A1. This is just a dummy code of my actual problem, the A1, A2 actually having 500 x 1 values.

t=['A1';'A2';'A3';'A4';'A5'];
for j=1:length(t)
    eval([t(j,:), '= 2*j'])
end

Can anyone help out how to deal with this problem in eval.

Do not create variables with dynamic names like this. It will cause you to write slow obfuscated code. It is better to use arrays, cell arrays, or struct variables. Read "TUTORIAL: Why Variables Should Not Be Named Dynamically (eval)" on MATLAB Answers for a detailed discussion.

eval(['t(',num2str(j),',:)= 2*',num2str(j)])
