This program ` matropt` could be used to check efficiency
of several implementations of the matrix by vector product:

<Vector 2> = <Matrix> <Vector 1>.The results may shown as follows:

Results: (for dimension 100000, cycles 100) -------- implementation CPU time ----------------------------------------- LASPack 1.967e-01 s = 100.0 % 1 2.836e-01 s = 144.2 % 2 2.326e-01 s = 118.3 % 3 1.928e-01 s = 98.0 % 4 2.005e-01 s = 101.9 % -----------------------------------------

For details to the implementations look at the file
` laspack/examples/matropt/testproc.c`.
The current ` LASPack`
version corresponds to the implementation 3.
This is, in comparison with ` LASPack`
, simplified and
can be therefore a little faster.
