import numpy as np mat = np.array([[1, 2, 3], [4, 5, 6]]) mat_transpose = mat.transpose()print(mat_tranpose)得到输出：[[14] [25] [36]]#original input[[1, 2, 3] [4, 5, 6]]原文链接：https://towardsdatascience.com/top-10-opencv-functions-everyone-has-to-know-...
但大多数情况下,不需要输出 Mat 中的所有数据,可以按行范围输出,如 0 ~ 2 行: #include <opencv2/imgproc/imgproc.hpp> #include <opencv2/highgui/highgui.hpp> #include <iostream> #include <iomanip> using namespace cv; using namespace std; ...
