Erfinv

Erfinv-func

Definition:

The x = erfinv(y) function is the inverse error function. The value of y must be in the interval [-1, 1]. It satisfies the error function y = erf(x) for -1 ≤ y ≤ 1 and -∞ ≤ x ≤ +∞.

Parameters:

y (input, double) 

The argument y of the function, must be within the range [-1, 1]

x (output, double)

The return value of the inverse error function for specified y.
