Detailed Description

BLAS Level 2 API.

trsv_strided_batched solves

 A_i*x_i = b_i or A_i**T*x_i = b_i,

where (A_i, x_i, b_i) is the i-th instance of the batch. x_i and b_i are vectors and A_i is an m by m triangular matrix, for i = 1, ..., batch_count.

The vector x is overwritten on b.

Parameters
[in]handle[rocblas_handle] handle to the rocblas library context queue.
[in]uplo[rocblas_fill] rocblas_fill_upper: A is an upper triangular matrix. rocblas_fill_lower: A is a lower triangular matrix.
[in]transA[rocblas_operation]
[in]diag[rocblas_diagonal] rocblas_diagonal_unit: A is assumed to be unit triangular. rocblas_diagonal_non_unit: A is not assumed to be unit triangular.
[in]m[rocblas_int] m specifies the number of rows of each b_i. m >= 0.
[in]Adevice pointer to the first matrix (A_1) in the batch, of dimension ( lda, m )
[in]stride_A[rocblas_stride] stride from the start of one A_i matrix to the next A_(i + 1)
[in]lda[rocblas_int] specifies the leading dimension of each A_i. lda = max( 1, m ).
[in,out]xdevice pointer to the first vector (x_1) in the batch.
[in]stride_x[rocblas_stride] stride from the start of one x_i vector to the next x_(i + 1)
[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
