Detailed Description

BLAS Level 2 API.

The tbsv 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 banded triangular matrix.

• 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]	k	- [int] if(uplo == HIPBLAS_FILL_MODE_UPPER), k specifies the number of super-diagonals of A. if(uplo == HIPBLAS_FILL_MODE_LOWER), k specifies the number of sub-diagonals of A. k >= 0.
[in]	AP	- device pointer storing the matrix A in banded format.
[in]	lda	- [int] specifies the leading dimension of A. lda >= (k + 1).
[in,out]	x	- device pointer storing input vector b. Overwritten by the output vector x.
[in]	incx	- [int] specifies the increment for the elements of x.
