[petsc-users] a cost question for sparse factorization

[Umut Tabak]

Dear all,

My question is not directly related to PETSc however it fits the 
audience on this list properly. Where can I find the computational cost 
analysis on

+ sparse cholesky factorization,
+ sparse LDL^T factorization,

in relation to the bandwidth of my sparse matrices. All the references I 
have present these costs for dense matrices. Where shall I look to get 
an overview on these costs for sparse/band matrices?

Best regards,
Umut
