说明：  OpenCV也提供了另一個資料結構來做Rand的實作,CvRandState,被包在"cvcompat.h"裡,"cvcompat.h"的完整意思是Computer Vision Compatility,CvRandState的特色是可以選定常態分佈及均勻分佈,不過,它只能運用在矩陣跟一維陣列.
(OpenCV also provides another data structure to do Rand' s implementation, CvRandState, was wrapped in " cvcompat.h" where, " cvcompat.h" means the integrity of Computer Vision Compatility, CvRandState features can be chosen normal distribution and uniform distribution, however, it can only be used in the matrix with the one-dimensional array.)
