I'm trying to make a simple menu system. I have all the variables I need in the workspace, and I have the name of the variable I want to access stored as a string, how do I open the workspace variable using that string?

However, using eval is a bad idea.
(I have taken the liberty of adapting some of Stephen Cobeldick's thoughts on this topic) Introspective programing (e.g. eval, assignin and other functions like it) is slow, and the MATLAB documentation warns specifically against it. Using eval is slow, makes debugging difficult, and removes all code helper tools (code checking, syntax hints, code completion, variable highlighting, etc.). A longer discussion can be found here. If you are not an expert and you think you need eval, there are probably better solutions to your problem. Also, if you are not an expert, you might find interesting and helpful hints on this page (and if you are an expert, you can still learn from it).

Figured out how, used the eval() function.
