erf

The error function.

Calling Sequence

y = erf(x)

Arguments

x

vector or matrix

y

vector or matrix (of same size than x)

Description

erf computes the error function:

Examples

deff('y=f(t)','y=exp(-t^2)');
erf(0.5)-2/sqrt(%pi)*intg(0,0.5,f)

x = [1+2*%i, -1+2*%i, 1e-6+2e-6*%i,0+2*%i];
a=erf(x)

// Equivalent to
1-erfc(x)

Algorithms

This function is based on the Faddeeva package library.
