Scales a Hermitian matrix.
Environmental enquiry function which returns values for tuning algorithmic performance.
This section describes the ScaLAPACK routines for solving systems of linear equations. Before calling most of these routines, you need to factorize the matrix of your system of equations (see Routines for Matrix Factorization in this chapter). However, the factorization is not necessary if your system of equations has a triangular matrix.
Provides error bounds and backward error estimates for the solution to a system of linear equations with a distributed triangular coefficient matrix.
Generates the unitary matrix Q of the LQ factorization formed by p?gelqf.
Multiplies a general matrix by the unitary transformation matrix from a reduction to upper triangular form determined by p?tzrzf.
Computes eigenvalues and (optionally) the Schur factorization of a matrix reduced to Hessenberg form.
Computes all eigenvalues and, optionally, eigenvectors of a complex Hermitian matrix.
Computes an LU factorization of a general triangular matrix with no pivoting. The routine is called by p?dbtrs.
