Sorry, but there are soooo many reasons why you do not want to create those numbered variables. Having now done so however, you still cannot just do something like "From A1 to AN". MATLAB does not support such an operation.
You need to convert your variables into an array. Learn to use arrays instead. I'm sorry. But just suck it up and get yourself out of the hole you climbed into. You can start over, creating an array, as you should have done in the beginning. Or you can type all those variable names. Hey, it is just once. It builds character. Or, you can dig even more deeply into that rabbit hole, finding a way to work with all those variables, perhaps still using eval. Good luck if you do that, if you choose to make the descent into programming hell. Better for you to simply climb out before the hole gets too deep.
