Detailed Description

!

BLAS Level 2 API

\details
xSPR_BATCHED performs the matrix-vector operations

    A_i := A_i + alphax_ix_iT

where alpha is a scalar, x_i is a vector, and A_i is an
n by n symmetric matrix, supplied in packed form, for i = 1, ..., batch_count.

@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'
          rocblas_fill_upper: The upper triangular part of each A_i is supplied in AP.
          rocblas_fill_lower: The lower triangular part of each A_i is supplied in AP.
@param[in]
n         [rocblas_int]
          the number of rows and columns of each matrix A_i, must be at least 0.
@param[in]
alpha
          device pointer or host pointer to scalar alpha.
@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 x_i.
@param[inout]
AP        device array of device pointers storing the packed version of the specified triangular portion of
          each symmetric matrix A_i of at least size ((n  (n + 1))  2). Array is of at least size batch_count.
          if uplo == rocblas_fill_upper:
            The upper triangular portion of each symmetric matrix A_i is supplied.
            The matrix is compacted so that AP contains the triangular portion column-by-column
            so that:
            AP(0) = A(0,0)
            AP(1) = A(0,1)
            AP(2) = A(1,1), etc.
                Ex: (rocblas_fill_upper; n = 4)
                    1 2 4 7
                    2 3 5 8   -----> [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
                    4 5 6 9
                    7 8 9 0
        if uplo == rocblas_fill_lower:
            The lower triangular portion of each symmetric matrix A_i is supplied.
            The matrix is compacted so that AP contains the triangular portion column-by-column
            so that:
            AP(0) = A(0,0)
            AP(1) = A(1,0)
            AP(2) = A(2,1), etc.
                Ex: (rocblas_fill_lower; n = 4)
                    1 2 3 4
                    2 5 6 7    -----> [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
                    3 6 8 9
                    4 7 9 0
@param[in]
batch_count [rocblas_int]
            number of instances in the batch.
