calerf

Arguments

x

real vector or matrix

erfType

0	: computes the error function erf(x)
1	: computes the complementary error function erfc(x)
2	: computes the scaled complementary error function erfcx(x)

y

real vector or matrix (of same size than x)

Examples

deff('y=f(t)','y=exp(-t^2)'); calerf(1,0) 2/sqrt(%pi)*intg(0,1,f)

Algorithms

This function is based on the Faddeeva package library.
