Error Message Examples

Second parameter, A, to GammaIInv, must be positive.

Cause

Function GammaIInv returns the inverse of the incomplete Gamma function. The function returns x such that

GammaI(x, a, b) = y.b

You have passed in a negative value as the second parameter, A, to GammaIInv, for which a Gamma function is not defined.

Correct the second parameter to the GammaIInv function to be a positive value.
