function cs_install (do_pause)
%CS_INSTALL: compile and install CSparse for use in MATLAB.
% Your current working directory must be CSparse/MATLAB in order to use this
% function.
%
% The directories
%
% CSparse/MATLAB/CSparse
% CSparse/MATLAB/Demo
% CSparse/MATLAB/UFget
%
% are added to your MATLAB path (see the "pathtool" command to add these to
% your path permanently, for future MATLAB sessions).
%
% Next, the MATLAB CSparse demo program, CSparse/MATLAB/cs_demo is executed.
% To run the demo with pauses so you can see the results, use cs_install(1).
% To run the full MATLAB test programs for CSparse, run testall in the
% Test directory.
%
% Example:
% cs_install % install and run demo with no pauses
% cs_install(1) % install and run demo with pauses
%
% See also: cs_demo
