class Point {
public:
Point(int, int);
double& operator()(int,int);
.......
protected:
int _ilen, _jlen;
double** _value;
};
Point::Point(int ilen, int jlen) {
_ilen=ilen;
_jlen=jlen;
_value=new double*[_ilen+2];
for(int i=0; i<=_ilen+1; i++) {
*(_value+i)=new double[_jlen+2];
for(int j=0; j<=_jlen+1; j++)
_value[i][j]=0;
}
}
double& Point::operator()(int i, int j) {
