Detailed Description

BLAS Level 2 API.

sbmv_batched performs the matrix-vector operation:

y_i := alpha*A_i*x_i + beta*y_i,

where (A_i, x_i, y_i) is the i-th instance of the batch. alpha and beta are scalars, x_i and y_i are vectors and A_i is an n by n symmetric banded matrix, for i = 1, ..., batch_count. A should contain an upper or lower triangular n by n symmetric banded matrix.

Parameters

[in]	handle	[rocblas_handle] handle to the rocblas library context queue
[in]	uplo	[rocblas_fill] specifies whether the upper 'rocblas_fill_upper' or lower 'rocblas_fill_lower' if rocblas_fill_upper, the lower part of A is not referenced if rocblas_fill_lower, the upper part of A is not referenced
[in]	n	[rocblas_int] number of rows and columns of each matrix A_i
[in]	k	[rocblas_int] specifies the number of sub- and super-diagonals
[in]	alpha	device pointer or host pointer to scalar alpha
[in]	A	device array of device pointers storing each matrix A_i
[in]	lda	[rocblas_int] specifies the leading dimension of each matrix A_i
[in]	x	device array of device pointers storing each vector x_i
[in]	incx	[rocblas_int] specifies the increment for the elements of each vector x_i
[in]	beta	device pointer or host pointer to scalar beta
[out]	y	device array of device pointers storing each vector y_i
[in]	incy	[rocblas_int] specifies the increment for the elements of each vector y_i
[in]	batch_count	[rocblas_int] number of instances in the batch
