Solves a system of linear matrix equations for a sparse matrix in the BSR format.
Solves a system of linear equations with a UDU- or LDL-factored symmetric matrix computed by ?sytrf and converted by ?syconv.
Refines the solution of a system of linear equations with a symmetric matrix and estimates its error.
Uses the diagonal pivoting factorization to compute the solution to the system of linear equations with a Hermitian matrix A stored in packed format, and provides error bounds on the solution.
Computes selected eigenvalues and eigenvectors of a real symmetric tridiagonal matrix.
Computes the product of a vector by a scalar.
Computes all eigenvalues and, optionally, eigenvectors of a real symmetric matrix in packed storage.
Computes matrix - vector product of a sparse symmetrical matrix stored in the CSR format (3-array variation) with one-based indexing.
