I need to do symbolic manipulations to very large systems of equations, and end up with well over 200 variables that I need to do computations with. The problem is, one would usually name their variables x, y, possibly z when solving small system of equations. Even starting at a, b, ... you only get 26 unique variables this way.
Is there a nice way of fixing this problem? Say for instance I wanted to fill up a 14x14 matrix with a different variable in each spot. How would I go about doing this?
