Detailed Description
BLAS Level 2 API.
tbsvStridedBatched solves
A_i*x_i = b_i or A_i**T*x_i = b_i or A_i**H*x_i = b_i,
where x_i and b_i are vectors and A_i is a banded triangular matrix, for i = [1, batchCount].
The input vectors b_i are overwritten by the output vectors x_i.
- Parameters
-
[in] handle [hipblasHandle_t] handle to the hipblas library context queue. [in] uplo [hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: A_i is an upper triangular matrix. HIPBLAS_FILL_MODE_LOWER: A_i is a lower triangular matrix. [in] transA [hipblasOperation_t] HIPBLAS_OP_N: Solves A_i*x_i = b_i HIPBLAS_OP_T: Solves A_i**T*x_i = b_i HIPBLAS_OP_C: Solves A_i**H*x_i = b_i [in] diag [hipblasDiagType_t] HIPBLAS_DIAG_UNIT: each A_i is assumed to be unit triangular (i.e. the diagonal elements of each A_i are not used in computations). HIPBLAS_DIAG_NON_UNIT: each A_i is not assumed to be unit triangular. [in] n [int] n specifies the number of rows of each b_i. n >= 0. [in] k [int] if(uplo == HIPBLAS_FILL_MODE_UPPER) k specifies the number of super-diagonals of each A_i. if(uplo == HIPBLAS_FILL_MODE_LOWER) k specifies the number of sub-diagonals of each A_i. k >= 0. [in] A device pointer pointing to the first banded matrix A_1. [in] lda [int] specifies the leading dimension of each A_i. lda >= (k + 1). [in] strideA [hipblasStride] specifies the distance between the start of one matrix (A_i) and the next (A_i+1). [in,out] x device pointer pointing to the first input vector b_1. Overwritten by output vectors x. [in] incx [int] specifies the increment for the elements of each x_i. [in] stridex [hipblasStride] specifies the distance between the start of one vector (x_i) and the next (x_i+1). [in] batchCount [int] number of instances in the batch.
