(4)void calcCovarMatrix( InputArray samples, OutputArray covar, OutputArray mean, int flags, int ctype=CV_64F) 其英文注释:computes covariation matrix of a set of samples 函数作用:计算矩阵行向量或列向量的协方差矩阵,该函数中会调用函数(3)来实现相应功能 (5)bool eigen(InputArray src, OutputArray ...
Eigen提供了一些基础的算法,如sum(),求所有元素和;prod(),求所有元素之积;mean...".*",对应元素做计算,所以两个Array相乘,只能是大小相同的Array。 Array提供了一些操作函数,abs(),求每个元素的绝对值;sqrt(),求每个元素的算术平方 Eigen矩阵库使用说明 为1的typedef) 注意第一句话:这个方法是针对于动态...
