%   				                   msf2c.m
%  Scope:   This MATLAB macro determines the real symmetric matrix stored as
%           columnwise upper triangular part as a one-dimensional array from 
%           its two-dimensional array.
%  Usage:   xout = msc2f(n,a)
%  Description of parameters:
%           n    - input, real scalar, number of rows and columns of the 
%                  symmetric matrix
%           a    - input, two-dimensional array storing the full symmetric
%                  matrix
%           xout - output, one-dimensional array of length  n*(n+1)/2, storing 
%                  columnwise the upper triangular part of the symmetric matrix
