        public double get​(int row,
                  int col)
        Description copied from interface: DMatrix
        Returns the value of value of the specified matrix element.
        Specified by:
        get in interface DMatrix
        Parameters:
        row - Matrix element's row index..
        col - Matrix element's column index.
        Returns:

      • unsafe_get

        public double unsafe_get​(int row,

        Description copied from interface: DMatrix
        Same as DMatrix.get(int, int) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.
        Specified by:
        unsafe_get in interface DMatrix
        Parameters:
        row - Matrix element's row index..

        Description copied from interface: DMatrix
        Sets the value of the specified matrix element.
        Specified by:
        set in interface DMatrix
        Parameters:
        row - Matrix element's row index..

        Description copied from interface: DMatrix
        Same as DMatrix.set(int, int, double) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.
        Specified by:
        unsafe_set in interface DMatrix
