calerf - computes error functions.

Parameters

• 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)
