public class DenseLargeIntMatrix2D extends WrapperIntMatrix2D
Implementation:
This data structure allows to store more than 2^31 elements. Internally holds one two-dimensional array, elements[rows][columns]. Note that this implementation is not synchronized.
Time complexity:
O(1) (i.e. constant time) for the basic operations get, getQuick, set, setQuick and size.

getQuick(int row,
int column)
Returns the matrix cell value at coordinate [row,column].
|
IntMatrix2D |
like(int rows,
int columns)
Construct and returns a new empty matrix of the same dynamic type
as the receiver, having the specified number of rows and columns.
|
IntMatrix1D |
like1D(int size)
Construct and returns a new 1-d matrix of the corresponding dynamic
type, entirelly independent of the receiver.
