.SH DESCRIPTION
\fIr.surf.gauss\fR produces a raster map of Gaussian deviates whose
mean and standard deviation can be expressed by the user. It uses a
Gaussian random number generator. It is essentially the same
as \fIr.surf.random\fR, but uses a
Gaussian random number generator instead.
.br
\fIHistogram of map generated with r.surf.gauss (mean=0, sigma=10)\fR
