Computes matrix - vector product of a sparse matrix stored in the CSR format.
Computes matrix - vector product for a sparse matrix in the diagonal format with one-based indexing.
Computes product of two sparse matrices stored in the CSR format (3-array variation) with one-based indexing. The result is stored in the dense matrix.
Computes the Bunch-Kaufman factorization of a complex Hermitian matrix.
Solves a system of linear equations with a UDU- or LDL-factored Hermitian matrix computed by ?hetrf and converted by ?syconv.
Estimates the reciprocal of the condition number of a packed symmetric matrix.
Refines the solution of a system of linear equations with a symmetric matrix and estimates its error.
Computes the inverse of a symmetric indefinite matrix through setting the leading dimension of the workspace and calling ?sytri2x.
Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive definite matrix in packed storage and reduce its condition number.
