Gaussian (VSL_RNG_METHOD_GAUSSIAN_ICDF)

Random number generator of normal (Gaussian) distribution with parameters a and s. You can obtain any successive random number x of the standard normal distribution by the inverse transformation method from the following formula:

where u is a random number uniformly distributed over the interval (-1, 1), and erf-1(u) is inverse to the error function .

The normal distribution with parameters a and s is transformed to the random number yby scaling and the shift y = sx+a.
