Parameters
xfloat, array-like, shape

The argument of the function, for .

Returns
ffloat, ndarray, shape

, the function values.

Raises
NagValueError
(errno )

On entry, .

Constraint: .

Notes

cdf_normal_vector evaluates approximate values of the cumulative Normal distribution function

for an array of arguments , for .

The function is based on the fact that

and it calls erfc_real() to obtain a value of for the appropriate argument.
