AFAIK there are no external checks that compare computed results with known 
data. There is a test directory in libs/numeric/ublas that contains concept 
checks and some benchmark that check matrix/vector multiplications. All 
results of specialized algorithms are compared to the result of the dense 
algorithm but if both fail the same way it will not be detected.
