int PLASMA_sgesvd ( PLASMA_enum  jobu, PLASMA_enum  jobvt, int  M, int  N, float *  A, int  LDA, float *  S, float *  U, int  LDU, float *  VT, int  LDVT, PLASMA_desc *  descT  ) PLASMA_sgesvd - computes the singular value decomposition (SVD) of a complex M-by-N matrix A, optionally computing the left and/or right singular vectors. The SVD is written A = U * SIGMA * transpose(V) where SIGMA is an M-by-N matrix which is zero except for its min(m,n) diagonal elements, U is an M-by-M orthogonal matrix, and V is an N-by-N orthogonal matrix. The diagonal elements of SIGMA are the singular values of A; they are real and non-negative, and are returned in descending order. The first min(m,n) columns of U and V are the left and right singular vectors of A. Note that the routine returns V**T, not V. Not LAPACK Compliant for now! Note: Only PlasmaNoVec supported! Parameters [in] jobu Specifies options for computing all or part of the matrix U. Intended usage: = PlasmaVec: all M columns of U are returned in array U; = PlasmaNoVec: no columns of U (no left singular vectors) are computed. Note: Only PlasmaNoVec supported! [in] jobvt Specifies options for computing all or part of the matrix V**T. Intended usage: = PlasmaVec: all M columns of U are returned in array U; = PlasmaNoVec: no columns of U (no left singular vectors) are computed. Note: Only PlasmaNoVec supported! [in] M The number of rows of the matrix A. M >= 0. [in] N The number of columns of the matrix A. N >= 0. [in,out] A On entry, the M-by-N matrix A. On exit, if JOBU = 'O', A is overwritten with the first min(m,n) columns of U (the left singular vectors, stored columnwise); if JOBVT = 'O', A is overwritten with the first min(m,n) rows of V**T (the right singular vectors, stored rowwise); if JOBU .ne. 'O' and JOBVT .ne. 'O', the contents of A are destroyed. [in] LDA The leading dimension of the array A. LDA >= max(1,M). [out] S The real singular values of A, sorted so that S(i) >= S(i+1). [out] U (LDU,M) if JOBU = 'A' or (LDU,min(M,N)) if JOBU = 'S'. If JOBU = 'A', U contains the M-by-M unitary matrix U; if JOBU = 'S', U contains the first min(m,n) columns of U (the left singular vectors, stored columnwise); if JOBU = 'N' or 'O', U is not referenced. [in] LDU The leading dimension of the array U. LDU >= 1; if JOBU = 'S' or 'A', LDU >= M. [out] VT If JOBVT = 'A', VT contains the N-by-N unitary matrix V**T; if JOBVT = 'S', VT contains the first min(m,n) rows of V**T (the right singular vectors, stored rowwise); if JOBVT = 'N' or 'O', VT is not referenced. [in] LDVT The leading dimension of the array VT. LDVT >= 1; if JOBVT = 'A', LDVT >= N; if JOBVT = 'S', LDVT >= min(M,N). [in,out] descT On entry, descriptor as return by PLASMA_Alloc_Workspace_sgesvd On exit, contains auxiliary factorization data. Returns Return values PLASMA_SUCCESS successful exit <0 if -i, the i-th argument had an illegal value See Also PLASMA_sgesvd_Tile PLASMA_sgesvd_Tile_Async PLASMA_cgesvd PLASMA_dgesvd PLASMA_sgesvd
