Parameters
[out]d_XSolution to the equation d_A * d_X = d_B.
[in]mNumber of rows in d_A.
[in]nNumber of columns in d_A, Number of rows in d_B.
[in]d_AThe co-efficient matrix.
[in]batch_AThe number of tiles of d_A being computed.
[in]kNumber of columns in d_B.
[in]d_BThe residual matrix.
[in]batch_BThe number of tiles of d_B being computed.
[in]optsGive specific information about the system.
optscombination (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
