Detailed Description

!

BLAS Level 2 API

\details
xSPMV_batched performs the matrix-vector operation:

    y_i := alphaA_ix_i + betay_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 matrix, for i = 1, ..., batch_count.
A should contain an upper or lower triangular n by n packed symmetric matrix.

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue
@param[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
@param[in]
n         [rocblas_int]
          number of rows and columns of each matrix A_i
@param[in]
alpha
          device pointer or host pointer to scalar alpha
@param[in]
A         device array of device pointers storing each matrix A_i
@param[in]
x         device array of device pointers storing each vector x_i
@param[in]
incx      [rocblas_int]
          specifies the increment for the elements of each vector x_i
@param[in]
beta      device pointer or host pointer to scalar beta
@param[out]
y         device array of device pointers storing each vector y_i
@param[in]
incy      [rocblas_int]
          specifies the increment for the elements of each vector y_i
@param[in]
batch_count [rocblas_int]
            number of instances in the batch
