Function direct

extensions/include/cuMat/src/SparseMatrix.h:230–233

* \brief Returns a wrapper class for direct coefficient access. * If this wrapper is used, a call to \ref coeff(Index row, Index col, Index batch, Index linear) const * will use the linear index instead of the regular row-column-batch index. This avoids * the search for the matching coefficient in this sparse matrix. * * The use case is the following optimization: *

     * \return a wrapper to trigger the direct-read optimization
