Device pointer interface: Solving linear systems.
Parameters: [out] d_X Solution to the equation d_A * d_X = d_B. [in] m Number of rows in d_A. [in] n Number of columns in d_A, Number of rows in d_B. [in] d_A The co-efficient matrix. [in] batch_A The number of tiles of d_A being computed. [in] k Number of columns in d_B. [in] d_B The residual matrix. [in] batch_B The number of tiles of d_B being computed. [in] opts Give specific information about the system. opts combination (sum) of: 0 for no information (solves using LU/CHOL for m == n, QR for m != n) 1 if d_A is positive definite 2 if d_A is not positive definite 3 Use Gaussian elimination (fast, cannot be combined with other options) 4 Use pseudo inverse (fast, cannot be combined with other options) 256 to do conjugate transpose on d_A before solving 512 to do transpose on d_A before solving 1024 if d_A is Upper triangular 2048 if d_A is Lower triangular
