Can GiNaC ME> solve nonlinear equations like this? Out of the box GiNaC can solve a linear system of equations only. For my package I wrote a routine which is resolving a system of linear equations and at most one additional quadratic equation. I do not think my coding may serve as a model, but you can see it anyway at Section G.5.5 here: https://sourceforge.net/projects/moebinv/files/docs/figure.pdf -- Vladimir V.
