The best solution is simply to not create lots of separate variables, but to store them all in one variable (numeric, cell, struct). This means you need to avoid having lots of numbered variables, and can simply access that one variable using indexing.

Whatever you do, do NOT try to create or access lots of numbered variables. This is very slow, buggy, and obfuscated way to code, as has been explained a thousand times on this forum:
