Detailed Description

BLAS Level 2 API.

tpsv_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 triangular matrix stored in the packed format, for i in [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: each A_i is an upper triangular matrix. rocblas_fill_lower: each A_i is a lower triangular matrix.
[in]transA[rocblas_operation] rocblas_operation_none: Solves A*x = b rocblas_operation_transpose: Solves A**T*x = b rocblas_operation_conjugate_transpose: Solves A**H*x = b
[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]APdevice array of device pointers storing the packed versions of each matrix A_i, of dimension >= (n * (n + 1) 2)
[in,out]xdevice array of device pointers storing each input vector b_i, overwritten by x_i on output.
[in]incx[rocblas_int] specifies the increment for the elements of each x_i.
[in]batch_count[rocblas_int] specifies the number of instances in the batch.
