erfinv - Inverse Error Function
Calling Sequence
-
x = erfinv(y)
Parameters
-
y
: real scalar, vector or matrix. Range of values is
[-1...+1]
-
x
: result of the inverse error function. x has same size as
x.
Description
-
X = ERFINV(Y) is the inverse error function for each element of Y.
The inverse error function satisfies y = erf(x), for -1 <= y <=
1 and -%inf <= x <= %inf. This function has been converted from
MatLab.
Examples
