| integer(kind(rocblas_status_success)) function | rocblas_ssbmv_batched_ (handle, uplo, n, k, alpha, a, lda, x, incx, beta, y, incy, batch_count) |
Detailed Description
BLAS Level 2 API.
The sbmv_batched functions perform 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 either 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.
