Calculates the complementary inverse error function evaluated at z.
Namespace: Altaxo.CalcAssembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax public static double ErfcInv(
double z
)
Parameters
- z Double
- value to evaluate.
Return Value
DoubleThe complementary inverse error function evaluated at given value.
Remarks We have tested this implementation against the arbitrary precision mpmath library
and found cases where we can only guarantee 9 significant figures correct.
- returns double.PositiveInfinity if z <= 0.0.
- returns double.NegativeInfinity if z >= 2.0.
