Syntax

y = erfcx(x)

Description

Computes the scaled complementary error function associated with a normal distribution. For all real x, erfcx(x) = exp(x^2)*erfc(x).

Examples

Inputs

Name	Description
x	Specifies error function values. x is a real scalar, vector, or matrix.

Outputs

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

Examples

% Compute the scaled complementary error function at 1.386:
Y = erfcx(1.386)
% Plot the scaled complementary error function:
X = 0:0.01:3;
Y = erfcx(X);
plot(X, Y)
