calerf

computes error functions.

Arguments

:x real vector or matrix : :flag integer indicator : :y real vector or matrix (of same size than x) :

Description

calerf(x,0) computes the error function erf(x)

calerf(x,1) computes the complementary error function erfc(x)

calerf(x,2) computes the scaled complementary error function erfcx(x)

Examples

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