◆ binaryExpr()

template<typename CustomBinaryOp , typename OtherDerived >

const CwiseBinaryOp<CustomBinaryOp, const Derived, const OtherDerived> binaryExpr	(	const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &	other,
		const CustomBinaryOp &	func = `CustomBinaryOp()`
	)		const

inline

Returns: an expression of a custom coefficient-wise operator func of *this and other

The template parameter CustomBinaryOp is the type of the functor of the custom operator (see class CwiseBinaryOp for an example)

Here is an example illustrating the use of custom functors:

#include <Eigen/Core>
#include <iostream>
 
using Eigen::Matrix4d;
 
// define a custom template binary functor
template<typename Scalar> struct MakeComplexOp {
  typedef std::complex<Scalar> result_type;
  result_type operator()(const Scalar& a, const Scalar& b) const { return result_type(a,b); }
};
 
int main(int, char**)
{
  Matrix4d m1 = Matrix4d::Random(), m2 = Matrix4d::Random();
  std::cout << m1.binaryExpr(m2, MakeComplexOp<double>()) << std::endl;
  return 0;
}

Code

Output:

   (0.68,0.271)  (0.823,-0.967) (-0.444,-0.687)   (-0.27,0.998)
 (-0.211,0.435) (-0.605,-0.514)  (0.108,-0.198) (0.0268,-0.563)
 (0.566,-0.717)  (-0.33,-0.726) (-0.0452,-0.74)  (0.904,0.0259)
  (0.597,0.214)   (0.536,0.608)  (0.258,-0.782)   (0.832,0.678)

Array3d v(-1,2,1), w(-3,2,3);

cout << ((v<w) && (v<0)) << endl;
