Detailed Description

BLAS Level 2 API.

tbsv_batched 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, batch_count].

The input vectors b_i are overwritten by the output vectors x_i.

Parameters
[in]handle[rocblas_handle] handle to the rocblas library context queue.
[in]uplo[rocblas_fill] rocblas_fill_upper: A_i is an upper triangular matrix. rocblas_fill_lower: A_i is a lower triangular matrix.
[in]transA[rocblas_operation] rocblas_operation_none: Solves A_i*x_i = b_i rocblas_operation_transpose: Solves A_i**T*x_i = b_i rocblas_operation_conjugate_transpose: Solves A_i**H*x_i = b_i
[in]diag[rocblas_diagonal] rocblas_diagonal_unit: each A_i is assumed to be unit triangular (i.e. the diagonal elements of each A_i are not used in computations). rocblas_diagonal_non_unit: each A_i is not assumed to be unit triangular.
[in]n[rocblas_int] n specifies the number of rows of each b_i. n >= 0.
[in]k[rocblas_int] if(uplo == rocblas_fill_upper) k specifies the number of super-diagonals of each A_i. if(uplo == rocblas_fill_lower) k specifies the number of sub-diagonals of each A_i. k >= 0.
[in]Adevice vector of device pointers storing each matrix A_i in banded format.
[in]lda[rocblas_int] specifies the leading dimension of each A_i. lda >= (k + 1).
[in,out]xdevice vector of device pointers storing each input vector b_i. Overwritten by each output vector x_i.
[in]incx[rocblas_int] specifies the increment for the elements of each x_i.
[in]batch_count[rocblas_int] number of instances in the batch.
