Dear All: I am solving a linear system Ax=b with about 40 millions DOF in PETSc. The solver is CR/Bjacobi. The driver is modified from source code : petsc-3.3-p6/src/ksp/ksp/examples/tutorials/ex10.c I am expecting the condition number of matrix A can be included in the output file but it doesn't now. I am wondering, is there any function or option eligible to print its condition number? thanks.
