How were these A1, A2, etc variables created in the first place? This is bad programming practice and leads to obfuscated code. The best thing for you to do is to first rewrite whatever code is producing those A1, A2, etc variables and get them into a single matrix or cell array to begin with. Then you can easily write code to do what you want to do with them. E.g., see this:

in this approach i have problem that when i create variables in dynamic way using loop or etc. i must put all values manually to each variables. i'm sure for economic researching i must put probably more than 50 variables data. and for your question i import data from excel and rename all VarNames to Ai ones.
