c++计算eigen随笔(7)-编译期指定大小矩阵

	
#include <iostream>
#include <../Eigen/Dense>
using namespace Eigen;
using namespace std;
int main()
{
  Matrix3d m = Matrix3d::Random();
  m = (m + Matrix3d::Constant(1.2)) * 50;
  cout << "m =" << endl << m << endl;
  Vector3d v(1,2,3);
  
  cout << "m * v =" << endl << m * v << endl;
}

m =
10.1251 90.8741 45.0291
66.3585 68.5009 99.5962
29.3304 57.9873  92.284
m * v =
326.961
502.149
