Performs reciprocal diagonal scaling on a vector.
Called from ?lamc2. Determines machine parameters given by beta, t, rnd, ieee1.
Solves a system of linear equations with a symmetric (Hermitian) positive-definite tridiagonal distributed matrix using the factorization computed by p?pttrf.
Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive definite distributed matrix and reduce its condition number.
Multiplies a general matrix by the orthogonal matrix Q of the QL factorization formed by p?geqlf.
Multiplies a general matrix by the unitary transformation matrix from a reduction to tridiagonal form determined by p?hetrd.
Table "ScaLAPACK Driver Routines" lists ScaLAPACK driver routines available for solving systems of linear equations, linear least-squares problems, standard eigenvalue and singular value problems, and generalized symmetric definite eigenproblems.
Computes all eigenvalues and eigenvectors of a complex Hermitian matrix by using a divide and conquer algorithm.
Forms the 1-norm of a complex vector similar to Level 1 PBLAS p?asum, but using the true absolute value.
