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:
-
x^3 + a*x^2 + b*x + c = 0
-
a*x^2 + b*x + c = 0
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 (x-1)^3 = 0 will have three roots with exactly equal values.
