erfi

Arguments

z

vector or matrix

y

vector or matrix (of same size than x)

Description

erfi computes the imaginary error function of x, defined by -i.erf(i.x).

Examples

erfi(1.234)

x = [-0.1, 0.1, 1, 1+2*%i,-1+2*%i,1e-6+2e-6*%i,0+2*%i];
erfi(x)
// equivalent to
-%i * erf(%i*x)

Algorithms

This function is based on the Faddeeva package library.
