long step = 0),在NdArray.Implicit.Array.cs中找到了NDArray到Array显性转换的实现,而NDArray有一个构造函数NDArray(Array values, Shape shape = default, char order = 'C'),Mat又有一个函数bool GetArray<T>(out T[] data)可以提取Array,有戏!
//void Create(CvMat* mat,int rows,int cols) { mat = cvCreateMat(rows,cols,CV_32FC1); } 1. 2. 3. 4. 5. 一开始使用的是注释掉的那一行,在调用这个函数之后,mat本应该被初始化的,但在后面的访问中会出现问题,后来将参数改为指针引用,才解决错误。 另一个问题是C++里面矩阵的定义是cv::mat,...
