      • convertToMatrixBlock

        static MatrixBlock convertToMatrixBlock​(FrameBlock frame,
                                                int k)
        Converts a frame block with arbitrary schema into a matrix block. Since matrix block only supports value type double, we do a best effort conversion of non-double types which might result in errors for non-numerical data.
        Parameters:
        frame - frame block
        k - parallelization degree
        Returns:
        matrix block
