Detailed Description
SOLVER API.
getrsStridedBatched solves a batch of systems of n linear equations on n variables in its factorized forms.
For each instance i in the batch, it solves one of the following systems, depending on the value of trans:
\[ \begin{array}{cl} A_i X_i = B_i & \: \text{not transposed,} A_i^T X_i = B_i & \: \text{transposed, or} A_i^H X_i = B_i & \: \text{conjugate transposed.} \end{array} \]
Matrix \(A_i\) is defined by its triangular factors as returned by hipblasSgetrfStridedBatched "getrfStridedBatched".
- Parameters
-
[in] handle hipblasHandle_t. [in] trans hipblasOperation_t.
Specifies the form of the system of equations of each instance in the batch.[in] n int. n >= 0.
The order of the system, i.e. the number of columns and rows of all A_i matrices.[in] nrhs int. nrhs >= 0.
The number of right hand sides, i.e., the number of columns of all the matrices B_i.[in] A pointer to type. Array on the GPU (the size depends on the value of strideA).
The factors L_i and U_i of the factorization A_i = P_i*L_i*U_i returned by hipblasSgetrfStridedBatched "getrfStridedBatched".[in] lda int. lda >= n.
The leading dimension of matrices A_i.[in] strideA hipblasStride.
Stride from the start of one matrix A_i to the next one A_(i+1). There is no restriction for the value of strideA. Normal use case is strideA >= lda*n.[in] ipiv pointer to int. Array on the GPU (the size depends on the value of strideP).
Contains the vectors ipiv_i of pivot indices returned by hipblasSgetrfStridedBatched "getrfStridedBatched".[in] strideP hipblasStride.
Stride from the start of one vector ipiv_i to the next one ipiv_(i+1). There is no restriction for the value of strideP. Normal use case is strideP >= n.[in,out] B pointer to type. Array on the GPU (size depends on the value of strideB).
On entry, the right hand side matrices B_i. On exit, the solution matrix X_i of each system in the batch.[in] ldb int. ldb >= n.
The leading dimension of matrices B_i.[in] strideB hipblasStride.
Stride from the start of one matrix B_i to the next one B_(i+1). There is no restriction for the value of strideB. Normal use case is strideB >= ldb*nrhs.[out] info pointer to a int on the host.
If info = 0, successful exit. If info = j < 0, the j-th argument is invalid.[in] batchCount int. batchCount >= 0.
Number of instances (systems) in the batch.
