Hi. Suppose I have these variables:
a=1
b=2
c=3
And I want to change their names by adding the number assigned here:
x = 1
So I will have:
a1= 1
b1= 2
c1= 3
Is possible to do that without a loop?
Thanks

There are certainly ways to do this, if you want to force yourself into writing slow, complex, buggy code that is hard to debug:

Much better is to learn how to use arrays and indexing, just like experienced MATLAB users. Indexing is neat, simple, easy to debug and very efficient. Unlike what you are trying to do.

Yes
a1 = a;
b1 = b;
c1 = c;
x is unneeded, as per this answer: Click here
and per the FAQ: How_can_I_create_variables_A1.2C_A2.2C....2C_A10_in_a_loop
Note though that a1 and a do not refer to the same memory location so changing a1 will not automatically change a, and changing a will not automatically change a1.

Thanks for your answer, though this solution is aplicable for the 3 variables I'm actually looking a way to do it for dozen of variables, thats why I used x=1 so if I changed x I can use it to modify multiple variable names at once.
