int PLASMA_zcgesv_Tile ( PLASMA_desc *  A, int *  IPIV, PLASMA_desc *  B, PLASMA_desc *  X, int *  ITER  ) PLASMA_zcgesv_Tile - Solves a system of linear equations using the tile LU factorization and mixed-precision iterative refinement. Tile equivalent of PLASMA_zcgesv(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors. Parameters [in,out] A On entry, the N-by-N coefficient matrix A. If the iterative refinement converged, A is not modified; otherwise, it fell back to double precision solution, and then A contains the tile L and U factors from the factorization (not equivalent to LAPACK). [out] IPIV On exit, the pivot indices that define the permutations (not equivalent to LAPACK). [in] B On entry, the N-by-NRHS matrix of right hand side matrix B. [out] X On exit, if return value = 0, the N-by-NRHS solution matrix X. [out] ITER The number of the current iteration in the iterative refinement process Returns Return values PLASMA_SUCCESS successful exit >0 if i, U(i,i) is exactly zero. The factorization has been completed, but the factor U is exactly singular, so the solution could not be computed. See Also PLASMA_zcgesv PLASMA_zcgesv_Tile_Async PLASMA_dsgesv_Tile PLASMA_zgesv_Tile
