Name
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)
