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.

• Supported precisions in rocBLAS : s, d, c, and z.
• Supported precisions in cuBLAS : s, d, c, and z.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	uplo	- [hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: A is an upper triangular matrix. HIPBLAS_FILL_MODE_LOWER: A is a lower triangular matrix.
[in]	transA	- [hipblasOperation_t] HIPBLAS_OP_N: Solves A*x = b HIPBLAS_OP_T: Solves A**T*x = b HIPBLAS_OP_C: Solves A**H*x = b
[in]	diag	- [hipblasDiagType_t] HIPBLAS_DIAG_UNIT: A is assumed to be unit triangular (that is, the diagonal elements of A are not used in computations). HIPBLAS_DIAG_NON_UNIT: A is not assumed to be unit triangular.
[in]	n	- [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	- [int] specifies the increment for the elements of x.
