Detailed Description

!

BLAS Level 3 API

\details

hemm_batched performs a batch of the matrix-matrix operations:

C_i := alphaA_iB_i + betaC_i if side == rocblas_side_left,
C_i := alphaB_iA_i + betaC_i if side == rocblas_side_right,

where alpha and beta are scalars, B_i and C_i are m by n matrices, and
A_i is a Hermitian matrix stored as either upper or lower.

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.

@param[in]
side  [rocblas_side]
        rocblas_side_left:      C_i := alphaA_iB_i + betaC_i
        rocblas_side_right:     C_i := alphaB_iA_i + betaC_i

@param[in]
uplo    [rocblas_fill]
        rocblas_fill_upper:  A_i is an upper triangular matrix
        rocblas_fill_lower:  A_i is a  lower triangular matrix

@param[in]
m       [rocblas_int]
        m specifies the number of rows of B_i and C_i. m >= 0.

@param[in]
n       [rocblas_int]
        n specifies the number of columns of B_i and C_i. n >= 0.

@param[in]
alpha
        alpha specifies the scalar alpha. When alpha is
        zero then A_i and B_i are not referenced.

@param[in]
A       device array of device pointers storing each matrix A_i on the GPU.
        A_i is m by m if side == rocblas_side_left
        A_i is n by n if side == rocblas_side_right
        Only the upperlower triangular part is accessed.
        The imaginary component of the diagonal elements is not used.

@param[in]
lda     [rocblas_int]
        lda specifies the first dimension of A_i.
        if side = rocblas_side_left,  lda >= max( 1, m ),
        otherwise lda >= max( 1, n ).

@param[in]
B       device array of device pointers storing each matrix B_i on the GPU.
        Matrix dimension is m by n

@param[in]
ldb     [rocblas_int]
        ldb specifies the first dimension of B_i. ldb >= max( 1, m )

@param[in]
beta
        beta specifies the scalar beta. When beta is
        zero then C_i need not be set before entry.

@param[in]
C       device array of device pointers storing each matrix C_i on the GPU.
        Matrix dimension is m by n

@param[in]
ldc    [rocblas_int]
       ldc specifies the first dimension of C_i. ldc >= max( 1, m )

@param[in]
batch_count [rocblas_int]
            number of instances in the batch.
