◆ cwiseEqual() [1/2]

template<typename OtherDerived >
const EIGEN_DEVICE_FUNC CwiseBinaryOp<numext::equal_to<Scalar>, const Derived, const OtherDerived> cwiseEqual ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other) const
inline
Returns
an expression of the coefficient-wise == operator of *this and other
Warning
this performs an exact comparison, which is generally a bad idea with floating-point types. In order to check for equality between two vectors or matrices with floating-point coefficients, it is generally a far better idea to use a fuzzy comparison as provided by isApprox() and isMuchSmallerThan().

Example:

MatrixXi m(2,2);
m << 1, 0,
1, 1;
cout << "Comparing m with identity matrix:" << endl;
cout << m.cwiseEqual(MatrixXi::Identity(2,2)) << endl;
Index count = m.cwiseEqual(MatrixXi::Identity(2,2)).count();
cout << "Number of coefficients that are equal: " << count << endl;

Output:

◆ cwiseEqual() [2/2]

const EIGEN_DEVICE_FUNC CwiseScalarEqualReturnType cwiseEqual ( const Scalar s) const
inline
Returns
an expression of the coefficient-wise == operator of *this and a scalar s
Warning
this performs an exact comparison, which is generally a bad idea with floating-point types. In order to check for equality between two vectors or matrices with floating-point coefficients, it is generally a far better idea to use a fuzzy comparison as provided by isApprox() and isMuchSmallerThan().

◆ cwiseMax() [1/2]

EIGEN_DEVICE_FUNC const EIGEN_STRONG_INLINE CwiseBinaryOp<internal::scalar_max_op<Scalar,Scalar>, const Derived, const OtherDerived> cwiseMax ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other) const
Returns
an expression of the coefficient-wise max of *this and other

Example:

Vector3d v(2,3,4), w(4,2,3);
cout << v.cwiseMax(w) << endl;

Output:

Returns

◆ cwiseMin() [2/2]

EIGEN_DEVICE_FUNC const EIGEN_STRONG_INLINE CwiseBinaryOp<internal::scalar_min_op<Scalar,Scalar>, const Derived, const ConstantReturnType> cwiseMin ( const Scalar other) const
Returns
an expression of the coefficient-wise min of *this and scalar other

◆ cwiseNotEqual()

template<typename OtherDerived >
const EIGEN_DEVICE_FUNC CwiseBinaryOp<numext::not_equal_to<Scalar>, const Derived, const OtherDerived> cwiseNotEqual ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other) const
inline
Returns
an expression of the coefficient-wise != operator of *this and other
Warning
this performs an exact comparison, which is generally a bad idea with floating-point types. In order to check for equality between two vectors or matrices with floating-point coefficients, it is generally a far better idea to use a fuzzy comparison as provided by isApprox() and isMuchSmallerThan().

Example:

MatrixXi m(2,2);
m << 1, 0,
1, 1;
cout << "Comparing m with identity matrix:" << endl;
cout << m.cwiseNotEqual(MatrixXi::Identity(2,2)) << endl;
Index count = m.cwiseNotEqual(MatrixXi::Identity(2,2)).count();
cout << "Number of coefficients that are not equal: " << count << endl;

template<typename OtherDerived >
EIGEN_DEVICE_FUNC const EIGEN_STRONG_INLINE CwiseBinaryOp<internal::scalar_quotient_op<Scalar>, const Derived, const OtherDerived> cwiseQuotient ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other) const
Returns
an expression of the coefficient-wise quotient of *this and other

Example:

Vector3d v(2,3,4), w(4,2,3);
cout << v.cwiseQuotient(w) << endl;

OtherDerived  ,
product   
) const &
Returns
an expression of the Schur product (coefficient wise product) of *this and other

Example:

Matrix3i a = Matrix3i::Random(), b = Matrix3i::Random();
Matrix3i c = a.cwiseProduct(b);
cout << "a:\n" << a << "\nb:\n" << b << "\nc:\n" << c << endl;
