function gbtest
%GBTEST test GraphBLAS MATLAB interface
% First compile the GraphBLAS library by typing 'make' in the top-level
% GraphBLAS folder, in your system shell.  That statement will use cmake to
% compile GraphBLAS.  Use 'make JOBS=40' to compile in parallel (replace '40'
% with the number of cores in your system).  Next, do the following in MATLAB:
%
% Example:
%
%   cd GraphBLAS/GraphBLAS
%   addpath (pwd) ;
%   savepath ;          % if this fails, edit your startup.m file
%   cd @GrB/private
%   gbmake ;            % compile the MATLAB interface to GraphBLAS
%   cd ../../test
%   gbtest              % run this test
%
% NOTE: All lines of all m-files are covered by this test, but the MATLAB
% profiler shows that some lines are untested.  All of these 'untested' lines
% are end statements that appear after an error ('...') statement, so they are
% not reachable.
