## Function Gaussian-Cdf

(

**gaussian-cdf** < x > &optional < mean > < sd > )

Computes the cumulative distribution function for a Gaussian random variable

(defaults: mean=0.0, s.d.=1.0) evaluated at ` x.' The result is the probability<br> of getting a random number less than or equal to `

x,' from the given Gaussian

distribution.
