Normal Distribution
Generates normally distributed random numbers.
Details
Normal (Gaussian) random number generator fills the input n x p numeric table with Gaussian random numbers with mean α and standard deviation σ, where α, σ∈R and σ > 0. The probability density function is given by:

The cumulative distribution function is as follows:
