GPS software toolbox for GPS receiver development

%                           range.m
%  Scope:   This MATLAB macro computes the range between two position points
%           defined into a three-dimensional orthogonal frame.
%  Usage:   xout = range(x1,x2)
%  Description of parameters:
%           x1   -  input, first position point
%           x2   -  input, second position point
%           xout -  output, range between the two defined position points
%  Remarks: 1) The computation is executed when the two vectors have the same
%              dimension (not only 3).
%           2) The components of the input vectors and the range should have 
%              the same unit, e.g. meters, feet.
