[petsc-users] Condition number of a matrix

[Tim Kroeger]

Dear PETSc team,

Is there some possibility in PETSc to compute (an approximation to) 
the condition number of a matrix?  The matrix is a rank-1 modification 
of a sparse matrix, and I am anyway using SuperLU_Dist to compute a 
factorization of the matrix.  The matrix is about 70000 times 70000.

Best Regards,

Tim
