I'm trying to find the inverse of the Error function in MMA.
I tried using InverseFunction, like this...
 InverseFunction[Erf[z]]
              (-1)
Out[1]= Erf[z]
But when I tried to find some numerical values i got this ...
In[2]:= % /. z->1 //N
                (-1)
Out[2]= 0.842701
Any help would be appreciated!
regards
Gus
