Syntax

y = erfcinv(x)

Description

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

Examples

Inputs

Name	Description
x	Specifies complementary error function values. x is a matrix with elements in the interval [0, 2].

Outputs

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

Examples

% Compute the inverse complementary error function at 1.386:
Y = erfcinv(1.386)
% Plot the inverse complementary error function:
X = 0:0.01:1.9;
Y = erfcinv(X);
plot(X, Y)
