name - series name (null not permitted).
Parameters:
rows - the number of rows.
Parameters:
columns - the number of columns. |
| equals | | public boolean equals(Object obj)(Code) | | Tests this object instance for equality with an arbitrary object.
Parameters:
obj - the object (null permitted). A boolean. |
| getColumnsCount | | public int getColumnsCount()(Code) | | Returns the number of columns in this matrix series.
The number of columns in this matrix series. |
| getItem | | public Number getItem(int itemIndex)(Code) | | Return the matrix item at the specified index. Note that this method
creates a new Double instance every time it is called.
Parameters:
itemIndex - item index. The matrix item at the specified index.
