[eigen] Array cwise multiplication

[Carlos Becker <carlosbecker@xxxxxxxxx>]

Hi all, I was trying to code something like this:

#include <Eigen/Dense>

using namespace Eigen;

using namespace std;

int main()

{

MatrixXf a;

VectorXf b;

a.resize(2,4);

b.resize(2);

a << 1,2,

3,4,

5,6,

7,8;

b << 1,2;

a = a.array().colwise() * b;

return 0;

}

Should this compile correctly? I want to multiply every column in matrix a, element-wise, with vector b, but I cannot make it work

I hope I am not forgetting about something important here.

Cheers,

Carlos
