opencv中矩阵赋值可以这么来

float Coordinates[ ]={
0.83,0.90,0.99,0.92,0.87,
326,285,340,287,310,
21,38,25,19,27,
3.2,2.4,2.2,2.0,0.9,
0.20,0.25,0.12,0.33,0.20,
0.15,0.20,0.14,0.09,0.15,
250,180,300,200,150,
0.23,0.15,0.27,0.30,0.18
};

CvMat* pData = cvCreateMat( 8, 5, CV_32FC1 );

cvSetData(pData,Coordinates,pData->step);

第二种赋值方法：

int main()
{
float k[9] = { 1.0, -2.0, 1.0, 4.0,

-2.0, -1.0, 4.0, -2.0, 2.0 };
CvMat km = cvMat( 3, 3, CV_32FC1, k
);

for (int i=0;i<3;i++)
{
for (int j=0;j<3;j++)
{

cout<<cvGet2D(&km,i,j).val[0];
cout<<" ";

}
cout<<endl;
}

return 0;
}
