%
%% NORMAL_SIMPLE creates normally distributed points.
%
%  Discussion:
%
%    The multivariate normal distribution has the form:
%
%      f(x) = (2*pi*det(V))**(-DIM_NUM/2) * exp(-0.5*(x-mu)'*inverse(V)*(x-mu))
%
%    where mu is the mean vector, and V is a positive definite symmetric
%    matrix called the variance-covariance matrix.
%
%    This routine implements the simplest version of a multivariate
%    normal distribution.  The variance-covariance matrix is the identity,
%    and the mean vector is entirely zero.  Thus, a sample on N points
%    is simply DIM_NUM*N scalar values generated under the univariate
%    normal distribution with zero mean and unit variance.
