vrf "inverse of the complementary error function"

Question asked by sordon on Jan 22, 2003
Bill Ossmann,

I know that. I will not use MatLab.
Is there anybody how can build the inverse of the erf ?

Thx, Stefan

Stefan,

If you are running VEE 6.0 or higher, the Matlab function erfinv(x) will
calculate the inverse error function.

Hello.
I need help.
I will calculate the "inverse of the complementary error function". But
I have only a formula for the normal error function (erf) and the
complementary error function (erf_c).

I know: inv_erf(1-X)=inv_erf_c(X)
How can I convert erf to the inv_erf ???
Can you send me a formula ???
Thanks

Note:
If you have a formula, you can check it: inv_erf_c(1E-9) = 4.32


            . (0 0) .
