int PLASMA_cgeqrs ( int  M, int  N, int  NRHS, PLASMA_Complex32_t *  A, int  LDA, PLASMA_desc *  descT, PLASMA_Complex32_t *  B, int  LDB  ) PLASMA_cgeqrs - Compute a minimum-norm solution min || A*X - B || using the RQ factorization A = R*Q computed by PLASMA_cgeqrf. Parameters [in] M The number of rows of the matrix A. M >= 0. [in] N The number of columns of the matrix A. N >= M >= 0. [in] NRHS The number of columns of B. NRHS >= 0. [in,out] A Details of the QR factorization of the original matrix A as returned by PLASMA_cgeqrf. [in] LDA The leading dimension of the array A. LDA >= M. [in] descT Auxiliary factorization data, computed by PLASMA_cgeqrf. [in,out] B On entry, the m-by-nrhs right hand side matrix B. On exit, the n-by-nrhs solution matrix X. [in] LDB The leading dimension of the array B. LDB >= max(1,N). Returns Return values PLASMA_SUCCESS successful exit <0 if -i, the i-th argument had an illegal value See Also PLASMA_cgeqrs_Tile PLASMA_cgeqrs_Tile_Async PLASMA_cgeqrs PLASMA_dgeqrs PLASMA_sgeqrs PLASMA_cgeqrf
