Polynomial.Solve (gb.gsl)
Function Solve ( [ Complex As Boolean ] ) As Array
Return the polynomial roots, i.e. solve the following equation: P(x) = 0
, provided that the polynomial coefficient are reals.

If Complex is TRUE, then all complex roots are returned.

If Complex is FALSE, then only the real roots are returned.
If no root is found, then a void array is returned.
If the polynomial has one of the following forms:
Then the algorithm will be as exact as possible.
Otherwise, a approximative algorithm will be used, that may not converge. In that case, an error is raised.
The case of coincident roots is not considered special. For example, the equation (x1)^3 = 0
will have three roots with exactly equal values.
