Eigen::Map<> on const array

Wed Aug 31, 2011 10:00 am
Hi, I would like to map a part of const array, it that possible?
Code: Select all
#include<eigen3/Eigen/Core>
using namespace Eigen;
int main(){
   const double a[4];
   Map<Vector2d> b(&a[1]);
}

obviously gives
Code: Select all
bb.cc:5:23: error: invalid conversion from ‘const double*’ to ‘double*’

Thanks!
