Solve a quartic equation in the form
For its purpose, it is assumed that ALL roots are double. This makes things faster.
[in] | b | coefficient of the quartic |
[in] | c | coefficient of the quartic |
[in] | d | coefficient of the quartic |
[in] | e | coefficient of the quartic |
[out] | z | vector containing the (double) roots of the quartic |
