%GBTEST test GraphBLAS 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:
%
% This test has been ported to Octave 7, as of SuiteSparse:GraphBLAS v5.1. A
% few features differ between Octave and MATLAB, so those tests are skipped for
% Octave. Octave passes all of the essential tests below.
%
% Example:
%
% cd GraphBLAS/GraphBLAS
% addpath (pwd) ;
% savepath ; % if this fails, edit your startup.m file
% cd @GrB/private
% gbmake ; % compile the interface to GraphBLAS
% cd ../../test
% gbtest % run this test
%
