Detailed Description

BLAS Level 2 API.

The tpsv 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 stored in the packed format.

The input vector b is overwritten by the output vector x.

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: 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: A is assumed to be unit triangular (the diagonal elements of A are not used in computations). 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]	AP	- device pointer storing the packed version of matrix A, of dimension >= (n * (n + 1) / 2).
[in,out]	x	- device pointer storing vector b on input, overwritten by x on output.
[in]	incx	- [rocblas_int] specifies the increment for the elements of x.
