                                  int col)
        Description copied from interface: Access2D
        Extracts one element of this matrix as a double.
        Parameters:
        row - A row index.
        col - A column index.
        Returns:
        One matrix element
      • firstInColumn

        public int firstInColumn​(int col)
        Description copied from interface: Structure2D
        The default value is simply 0, and if all elements are zeros then this.countRows().

        Returns:
        The row index of the first non-zero element in the specified column
      • firstInRow

        public int firstInRow​(int row)
        Description copied from interface: Structure2D
        The default value is simply 0, and if all elements are zeros then this.countColumns().
        Returns:
        The column index of the first non-zero element in the specified row
      • get

        public N get​(int row,
                     int col)
      • limitOfColumn

        public int limitOfColumn​(int col)
        Description copied from interface: Structure2D
        The default value is simply this.countRows(), and if all elements are zeros then 0.

        Returns:
        The row index of the first zero element, after all non-zeros, in the specified column (index of the last non-zero + 1)
      • limitOfRow

        public int limitOfRow​(int row)
        Description copied from interface: Structure2D
        The default value is simply this.countColumns(), and if all elements are zeros then 0.
