/**
* TestMatrix tests the functionality of the Jama Matrix class and associated decompositions.
<P>
Detailed output is provided indicating the functionality being tested
and whether the functionality is correctly implemented. Exception handling
is also tested.
<P>
The test is designed to run to completion and give a summary of any implementation errors
encountered. The final output should be:
<BLOCKQUOTE><PRE><CODE>
TestMatrix completed.
Total errors reported: n1
Total warning reported: n2
</CODE></PRE></BLOCKQUOTE>
If the test does not run to completion, this indicates that there is a
substantial problem within the implementation that was not anticipated in the test design.
The stopping point should give an indication of where the problem exists.
