Re: [eigen] Eigen Internals

[ Thread Index | Date Index | More Archives ]


that's a though question! Which part do you want to learn?

Anyhow, a good start could be to run step by step in a debugger the following code:

#include <Eigen/Core>
using namespace Eigen;
int main() {
  int n = 5;
  VectorXd A(n), B(n), C(n);
  A = B+C;

This will show you what is returned by A+B, and how this simple _expression_ is evaluated. You can comment #define  EIGEN_DONT_VECTORIZE  to see how explicit vectorization is accomplished or try more fancy expressions.

I have been going through the core Eigen folder. I am really confused about the starting point of it all as from which header file I should start understanding the Eigen internals and function definitions.
