Condition number
 
Hi All,

is it possible to calculate condition number of the class fvMatrix? Well, I'm looking for some criteria, which would describe the conditionality of the equation system.

Thanks.

Computing the condition number of a matrix requires computing eigenvalues. Computing eigenvalues of a big sparse matrix resulting from discretization of a mesh is somewhat also hard than solving Navier Stokes system.
Maybe you should say why you need such a computation. Are you really really sure it is necessary?
