integer(kind(rocblas_status_success)) function	rocblas_strsv_batched_ (handle, uplo, transa, diag, n, a, lda, x, incx, batch_count)

Detailed Description

BLAS Level 2 API.

The trsv_batched functions solve:

 A_i*x_i = b_i or
 A_i**T*x_i = b_i or
 A_i**H*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 n by n triangular matrix.

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] rocblas_operation_none: op(A) = A. rocblas_operation_transpose: op(A) = A^T. rocblas_operation_conjugate_transpose: op(A) = A^H.
[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]	n	- [rocblas_int] n specifies the number of rows of b. n >= 0.
[in]	A	- device pointer to an array of device pointers to the A_i matrices, of dimension ( lda, n ). If uplo == rocblas_fill_upper, the upper triangular part of the leading n-by-n array contains the matrix A_i. Otherwise, the lower triangular part of the leading n-by-n array contains the matrix A_i.
[in]	lda	- [rocblas_int] specifies the leading dimension of A_i. lda must be at least max( 1, n ).
[in,out]	x	- device pointer to an array of device pointers to the x_i vectors. On exit, each x_i is overwritten with the transformed vector x_i.
[in]	incx	- [rocblas_int] specifies the increment for the elements of x.
[in]	batch_count	- [rocblas_int] number of instances in the batch.
