I am trying to calculate the condition number of a Trilinos Block Sparse
matrix. Is there an example of that in the documentation that you can point me to?
No, and that's actually a quite difficult task because you have to estimate
eigenvalues. The easiest way is probably to use the power iteration and
inverse power iteration to estimate largest and smallest eigenvalues -- see
the EigenPower and EigenInverse classes.
