How do I cite Cusp?

Functionality

Does Cusp support dense matrices?

Short answer: Yes, but only for a limited set of purposes.

Long answer: Cusp provides an array2d container for dense matrices and supports many operations on dense matrices. However, Cusp is focused on sparse matrix operations and does not subsume the functionality provided by BLAS or LAPACK libraries. For instance, while the iterative solvers employed by Cusp are efficient for sparse matrices, they can seldom compete with factorization methods on dense matrices. If your linear system is dense, you will almost certainly obtain better performance by using one of the libraries designed for solving dense linear systems.

Hi I want to implement CUSP library on a large non symmetric sparse matrix. SUPER LU solve my problem but when I use cusp liner solvers (all of them) residual will be diverged! Could any one help me in this problem?(hajji.alireza@gmail.com)
