This is the GraphBLAS/Demo folder. It contains a set of simple demo programs
that illustrate the use of GraphBLAS. To compile and run the demos, see
../README.txt.
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
>>> DO NOT BENCHMARK ANY OF THESE PROGRAMS <<<
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These methods are simple ones, meant for illustration only. They can be
slow. Use LAGraph for benchmarking and use in production. Do not use any
of these methods in user applications. Eventually, this Demo folder will
be removed, and its purpose will be achieved in LAGraph instead.
