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)');
