This is an internal interface and not for user usage. It exposes a specialised subset of BLAS/LAPACK functionality. This functionality is used by us to build the exposed APIs. It is those exposed APIs that should be used.

|
|
Returns the full Singular Value Decomposition of the input MxN matrix A : A = U * SIGMA * V**T in the tuple (S, U, V**T), where S is an array containing the diagonal elements of SIGMA. uses the LAPACK routine dgesdd with the argument JOBZ = 'A'
|
|
Returns the thin Singular Value Decomposition of the input MxN matrix A A = U * SIGMA * V**T in the tuple (S, U, V**T), where S is an array containing the diagonal elements of SIGMA. The first min(M,N) columns of U and the first min(M,N) rows of V**T are returned in the arrays U and VT; uses the LAPACK routine dgesdd with the argument JOBZ = 'S'

|
Computes for a N-by-N real symmetric matrix A, the eigenvalue decomposition of eigenvalues and right eigenvectors. The right eigenvector v(j) of A satisfies A * v(j) = lambda(j) * v(j) where lambda(j) is its eigenvalue.
