addrelpath.m

Matlab toolbox that contains functions of Kalman filter and random system simulation.

% ADDRELPATH  Add a relative path which gets expanded into a absolute path
%             to the front of MATLABPATH.
%
%     addrelpath(path_string)
%
%     INPUT
%            path_string        : string containing relative path
%
%
%     Example : addrelpath('../foo');
%
%     This will first expand '../foo' to an absolute path and then add it to the
%     front of MATLABPATH
