public class SparseMatrix
{
static SparseObjectMatrix2D matrix = new SparseObjectMatrix2D(1000000, 1000000);
public static void main(String[] args)
{
matrix.set(1, 2, 3.0);
}
}
Here is the error that I'm getting:
java.lang.ExceptionInInitializerError Caused by:
java.lang.IllegalArgumentException: matrix too large at

You cannot. From the documentation:
Throws:
IllegalArgumentException
- ifrows<0 || columns<0 || > (double)columns*rows > Integer.MAX_VALUE
.
Instead of creating a matrix addressed with x and y coordinates, returning a Value
, create a HashMap<Coordinates, Value>
, where Coordinates
is a simple class holding x and y.
