I'm working with equations like I_1, I_2, I_3, and so on. All of which have the same function definition like I_1=A_1*B_1 where each variable has a unique value. Creating these variables with syms command is a bit excessive if I include all of the variables. Does anyone have an Idea to declare these variables in one go?

You could create arrays of I,A and B like this:
I = sym('I_',[1 3]);
A =sym('A_',[1 3]);
B =sym('B_',[1 3]);
you will get I,A and B as array of the required variables
