Detailed Description

BLAS Level 2 API.

tbsv solves

 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.

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 (i.e. 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]k[rocblas_int] if(uplo == rocblas_fill_upper) k specifies the number of super-diagonals of A. if(uplo == rocblas_fill_lower) k specifies the number of sub-diagonals of A. k >= 0.
[in]Adevice pointer storing the matrix A in banded format.
[in]lda[rocblas_int] specifies the leading dimension of A. lda >= (k + 1).
[in,out]xdevice pointer storing input vector b. Overwritten by the output vector x.
[in]incx[rocblas_int] specifies the increment for the elements of x.
