  Algorithm 980: sparse QR factorization on the GPU
Yeralan S., Davis T., Sid-Lakhdar W., Ranka S. ACM Transactions on Mathematical Software 44(2): 1-29, 2017.  Type: Article

Many large-scale scientific and engineering computational problems lead, after some kind of discretization, to the solution of huge systems of linear algebraic equations and/or linear least squares problems containing many hundreds of ...

  Algorithm 933: reliable calculation of numerical rank, null space bases, pseudoinverse solutions, and basic solutions using SuiteSparseQR
Foster L., Davis T. ACM Transactions on Mathematical Software 40(1): 1-23, 2013.  Type: Article

The rank is one of the major characteristics of a matrix. In practice, the rank is not clear cut due to measurement errors and/or noise. Thus, determining the numerical rank of a matrix is an important problem. Many applications requir...

  Algorithm 915, SuiteSparseQR: multifrontal multithreaded rank-revealing sparse QR factorization
Davis T. ACM Transactions on Mathematical Software 38(1): 1-22, 2011.  Type: Article

In the area of computational linear algebra, an important topic is the solution of sparse matrix problems and the development of quality software. These problems require solution linear systems of equations and least-square problems. T...
