OpenCV 寻找最大\最小值，返回值和位置

int main()

Mat temp = Mat::zeros(1,5,CV_64F); 
temp.at<double>(0,0) = 4;
temp.at<double>(0,1) = 3;
temp.at<double>(0,2) = 1;
temp.at<double>(0,3) = 10;
temp.at<double>(0,4) = 1;
double minVal; double maxVal; Point minLoc; Point maxLoc;
minMaxLoc(temp, &minVal, &maxVal, &minLoc, &maxLoc);
cout << temp << endl;
cout << minVal << " " << maxVal << " " << minLoc.x << " " << maxLoc.x << endl;
system("pause");
return 0;
