Syntax

y = erf_inv(x)

Legacy Name: erfinv

Description

Computes the inverse of the error function associated with a normal distribution. y = erf_inv(x) is equivalent to x = erf(y).

Examples

Inputs

Name Description
x Specifies error function values. x is a real matrix with elements in the interval [-1, 1].

Outputs

Name Description
y Returns the value of the inverse error function of x.
