- - ### Method Detail

    - #### get

          double get(int x,
                     int y)

      Parameters:
        `x` - Matrix row index.
        `y` - Matrix column index.
      Returns:
        Value corresponding to given row and column.

    - #### set

          void set(int x,
                   int y,
                   double v)

      Parameters:
        `x` - Matrix row index.
        `y` - Matrix column index.
        `v` - Value to set at given row and column.

    - #### columnSize

          int columnSize()

    - #### rowSize

          int rowSize()

    - #### storageMode

          int storageMode()

      Returns:
        Matrix elements storage mode.
      See Also:
        `StorageConstants`

    - #### accessMode

          int accessMode()

      Returns:
        Matrix access mode.
      See Also:
        `StorageConstants`

    - #### data

          default double[] data()

      Gets underlying data, if `StorageOpsMetrics.isArrayBased()` returns `false` this method return copy of data. The data must be adapted for `Blas`.
      See Also:
        `StorageOpsMetrics.isArrayBased()`

    - #### isNumeric

          default boolean isNumeric()

      Specified by:
        `isNumeric` in interface `StorageOpsMetrics`
      Returns:
        true if all stored data are values of Number class.
