erfinv
The inverse of the error function.
y=erfinv(p)
Inputs
x a real array or a real scalar.
Outputs
y the array of values of the inverse of the error function at the values specified by the elements of the input.


Description
The result satisfies erf(y)=p. Clearly, the absolute value of the inputs must be less than 1.


Example
>>x=-.999:.001:.999
>>y=erfinv(x)
>>plot(x,y)
>>title('Inverse of the Error Function')
>>xlabel('X-Axis')
>>ylabel('Y Axis')
