CvMat执行CvReshape()报错“The matrix is not continuous, thus its number of rows can not be changed”

CvMat执行CvReshape()报错“The matrix is not continuous, thus its number of rows can not be changed”，采用如下处理方式：

       重新生成一个全新的矩阵，具有相同的数据，那么数据就是连续的，就能执行reshape()函数操作。

Mat patchMatTmp;
patchMat.copyTo(patchMatTmp);

patchColMat = patchMatTmp.reshape(1,nWindow*nWindow);
