Detailed Description

template<typename ExpressionType>
class Cwise< ExpressionType >

Pseudo expression providing additional coefficient-wise operations.

Parameters:
ExpressionTypethe type of the object on which to do coefficient-wise operations

This class represents an expression with additional coefficient-wise features. It is the return type of MatrixBase::cwise() and most of the time this is the only way it is used.

Example:

#define EIGEN2_SUPPORT
#include <Eigen/Core>
#include <iostream>

using namespace Eigen;
using namespace std;

int main()
{
  Matrix3i m = Matrix3i::Random();
  cout << "Here is the matrix m:" << endl << m << endl;
  Matrix3i n = Matrix3i::Random();
  cout << "And here is the matrix n:" << endl << n << endl;
  cout << "The coefficient-wise product of m and n is:" << endl;
  cout << m.cwise() * n << endl;
  cout << "Taking the cube of the coefficients of m yields:" << endl;
  cout << m.cwise().pow(3) << endl;
}

Output:

This class can be extended with the help of the plugin mechanism described on the page Customizing/Extending Eigen by defining the preprocessor symbol EIGEN_CWISE_PLUGIN.
