I want to draw a TMatrixD object. But I can't. 

------------------------------------------------------
#include <iostream>
using namespace std;

#include "TMatrix.h"

int main(void)
{
	int i,j;

	TMatrix E(10,10);

	for(i=0;i<10;i++)
		for(j=0;j<10;j++)
			E(i,j) = i*j;

	for(i=0;i<10;i++)
		for(j=0;j<10;j++)
			printf("%f\n",E(i,j));

	E.Draw("SURF");

	getchar();

	return(0);
}// end of main
------------------------------------------------------

This code draw only empty window. What's wrong?
