%                             gauss_1.m
%  Scope:   This MATLAB macro computes the probability density function of the
%           normal Gaussian distribution.
%  Usage:   xoutput = gauss_1(x,y)
%  Description of parameters:
%           x       - input, scalar independent variable
%           y       - input, scalar dependent variable
%           xoutput - output, computed probability density function 
%  Remark:  This macro can be used for the computation of the integral of the
%           probability density function.
