## 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 [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 (i.e. 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] A 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.
