Multiplies a general matrix by the orthogonal/unitary matrix from a RQ factorization determined by ?gerqf (unblocked algorithm).
Computes the eigenvalues of a Hessenberg matrix, and optionally computes the matrices from the Schur decomposition.
Reduces a general matrix to bidiagonal form using an unblocked algorithm.
Determines machine parameters for floating-point arithmetic.
Returns the value of the 1-norm, or the Frobenius norm, or the infinity norm, or the element of largest absolute value of a triangular matrix supplied in packed form.
Generates the unitary matrix Q of the QL factorization formed by p?geqlf.
Computes the SVD of a real bidiagonal matrix with diagonal d and off-diagonal e. Used by ?bdsdc.
Finds the element with maximum real part absolute value and its corresponding global index.
Computes a QR factorization of a real or complex "triangular-pentagonal" matrix, which is composed of a triangular block and a pentagonal block, using the compact WY representation for Q.
Computes the infinity norm condition number of op(A)*inv(diag(c)) for Hermitian indefinite matrices.
