I don't know your code and, as mentioned before, I didn't really understand the question. But in 99 % of the cases using eval is not the best idea. Besides issues such as slow execution, it makes debugging very difficult. There are cases when eval is the best (or the only) way, but that's limited to the 1 % remaining in my statistics. In all other cases, I'd not recommend it.

You can allocate that string to a variable, and use that variable in the next function:
str = firstFunction(...);
secondFunction(str)
This will call the second function with whatever string the first function returned.
If you are talking about using a string to dynamically name a variable, then don't do this and use a cell array or structure instead.
