                       throws ApfloatRuntimeException
        Transform the columns of a matrix using a 3-point transform.
        Parameters:
        dataStorage0 - The data of the first column.
        dataStorage1 - The data of the second column.
        dataStorage2 - The data of the third column.
        startColumn - The starting element index in the data storages to transform.
        columns - How many columns to transform.
        power2length - Length of the column transform.
        length - Length of total transform (three times the length of one column).
        isInverse - true if an inverse transform is performed, false if a forward transform is performed.
        modulus - Index of the modulus.
        Throws:
        ApfloatRuntimeException
