Available Subroutines and Prototype Codes

ScaLAPACK, Version 1.5 + update (version 1.6)

This release of ScaLAPACK includes routines for

• the solution of linear systems of equations,
• general and symmetric positive definite band linear systems of equations,
• general and symmetric positive definite tridiagonal linear systems of equations,
• condition estimation and iterative refinement for LU and Cholesky factorization,
• matrix inversion,
• full-rank linear least squares problems,
• orthogonal and generalized orthogonal factorizations,
• orthogonal transformation routines,
• reductions to upper Hessenberg, bidiagonal and tridiagonal form,
• reduction of a symmetric-definite generalized eigenproblem to standard form,
• the symmetric/Hermitian eigenproblem,
• the generalized symmetric/Hermitian eigenproblem,
• the nonsymmetric eigenproblem, and
• the singular value decomposition.

ScaLAPACK routines are available in four types: single precision real, double precision real, single precision complex, and double precision complex. At the present time, the nonsymmetric eigenproblem is only available in single and double precision real.
