Hi,

I'm looking for a way to solve a system of nonlinear equations, similar to the functionality of cSolve function on a TI 89. User input will be an nxn matrix.

Can/will anyone provide me with a quick and efficient way to do this with Eigen?

Thanks

that depends on the kind of problem. Have a look there:
