bug in the code...

[stiv-yakovenko]

this gives a crash:

double a[]={2.0000000000025215, 1.5000000000025215, 0.5, -0.0625};
double r[5];
quarticSolver(a,r);

Hi stiv,

Please note this quartic solver is outdated, and is there only for
explanatory purposes.

If you are interested in some mature quartic solver code, please have a
look at the Eigen library's polynomial solver, and one example can be found
at:

Best Regards,
