Function Documentation

template<typename CustomBinaryOp , typename OtherDerived >
EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const CwiseBinaryOp<CustomBinaryOp, const Derived, const OtherDerived> binaryExpr ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other,
const CustomBinaryOp &  func = CustomBinaryOp() 
) const
Returns
an expression of the difference of *this and other
Note
If you want to substract a given scalar from all coefficients, see Cwise::operator-().
See also
class CwiseBinaryOp, operator-=()
Returns
an expression of the sum of *this and other
Note
If you want to add a given scalar to all coefficients, see Cwise::operator+().
See also
class CwiseBinaryOp, operator+=()
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 namespace Eigen;
using namespace std;
// define a custom template binary functor
template<typename Scalar> struct MakeComplexOp {
typedef complex<Scalar> result_type;
complex<Scalar> operator()(const Scalar& a, const Scalar& b) const { return complex<Scalar>(a,b); }
};
int main(int, char**)
{
Matrix4d m1 = Matrix4d::Random(), m2 = Matrix4d::Random();
cout << m1.binaryExpr(m2, MakeComplexOp<double>()) << endl;
return 0;
}

Output:

template<typename OtherDerived >
EIGEN_DEVICE_FUNC const CwiseBinaryOp<internal::scalar_boolean_and_op, const Derived, const OtherDerived> operator&& ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other) const
inline
Returns
an expression of the coefficient-wise boolean and operator of *this and other
Warning
this operator is for expression of bool only.

Example:

Array3d v(-1,2,1), w(-3,2,3);
cout << ((v<w) && (v<0)) << endl;

Output:

operator||(), select()

template<typename OtherDerived >
EIGEN_DEVICE_FUNC const CwiseBinaryOp<internal::scalar_boolean_or_op, const Derived, const OtherDerived> operator|| ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other) const
inline
Returns
an expression of the coefficient-wise boolean or operator of *this and other
Warning
this operator is for expression of bool only.

Example:

Array3d v(-1,2,1), w(-3,2,3);
cout << ((v<w) || (v<0)) << endl;

Output:

See also
operator&&(), select()
