Detailed Description

BLAS Level 2 API.

tbsvStridedBatched solves

 A_i*x_i = b_i or A_i**T*x_i = b_i or A_i**H*x_i = b_i,

where x_i and b_i are vectors and A_i is a banded triangular matrix, for i = [1, batchCount].

The input vectors b_i are overwritten by the output vectors x_i.

Parameters

[in]	handle	[hipblasHandle_t] handle to the hipblas library context queue.
[in]	uplo	[hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: A_i is an upper triangular matrix. HIPBLAS_FILL_MODE_LOWER: A_i is a lower triangular matrix.
[in]	transA	[hipblasOperation_t] HIPBLAS_OP_N: Solves A_i*x_i = b_i HIPBLAS_OP_T: Solves A_i**T*x_i = b_i HIPBLAS_OP_C: Solves A_i**H*x_i = b_i
[in]	diag	[hipblasDiagType_t] HIPBLAS_DIAG_UNIT: each A_i is assumed to be unit triangular (i.e. the diagonal elements of each A_i are not used in computations). HIPBLAS_DIAG_NON_UNIT: each A_i is not assumed to be unit triangular.
[in]	n	[int] n specifies the number of rows of each b_i. n >= 0.
[in]	k	[int] if(uplo == HIPBLAS_FILL_MODE_UPPER) k specifies the number of super-diagonals of each A_i. if(uplo == HIPBLAS_FILL_MODE_LOWER) k specifies the number of sub-diagonals of each A_i. k >= 0.
[in]	A	device pointer pointing to the first banded matrix A_1.
[in]	lda	[int] specifies the leading dimension of each A_i. lda >= (k + 1).
[in]	strideA	[hipblasStride] specifies the distance between the start of one matrix (A_i) and the next (A_i+1).
[in,out]	x	device pointer pointing to the first input vector b_1. Overwritten by output vectors x.
[in]	incx	[int] specifies the increment for the elements of each x_i.
[in]	stridex	[hipblasStride] specifies the distance between the start of one vector (x_i) and the next (x_i+1).
[in]	batchCount	[int] number of instances in the batch.
