Inverse Error Function

[etowie]

Hi there,

I know that Intel Fortran has some very nice intrinsic functions for calculating the Error Function (ERF(x)) and the Complementary Error Function (ERFC(x)), but I can't seem to find a function for the Inverse Error Function (erf^-1(x)).

There appears to be an inverse error function defined in the Math Kernel Library but this is for vectors! Is there a function avaiable somewhere to compute the inverse error function for scalars??

Any help would be appreciated :-)

I am guessing that this is perhaps not the correct forum for this question..

There is no intrinsic inverse error function in Fortran. If you want to use the MKL function, you can put the scalar in a 1 element array.
