Detailed Description

BLAS Level 2 API.

The trsv functions solve:

 A*x = b or
 A**T*x = b or
 A**H*x = b,

where x and b are vectors and A is a triangular matrix. The vector x is overwritten on b.

Although not widespread, some GEMM kernels used by trsv might use atomic operations. See Atomic Operations in the API Reference Guide for more information.

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 storing matrix A, of dimension ( lda, n ). If uplo == rocblas_fill_upper, the upper triangular part of the leading n-by-n array contains the matrix A. Otherwise, the lower triangular part of the leading n-by-n array contains the matrix A.
[in]	lda	- [rocblas_int] specifies the leading dimension of A. lda must be at least max( 1, n ).
[in,out]	x	- device pointer storing vector x. On exit, x is overwritten with the transformed vector x.
[in]	incx	- [rocblas_int] specifies the increment for the elements of x.
