const EIGEN_CWISE_PRODUCT_RETURN_TYPE ( Derived  ,
OtherDerived   
) const [inline]
Returns:
an expression of the coefficient wise product of *this and other
See also:
MatrixBase::cwiseProduct

References EIGEN_CWISE_PRODUCT_RETURN_TYPE.

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 && 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:

0
0
0
See also:
operator||(), select()

References EIGEN_STATIC_ASSERT.

const CwiseUnaryOp<internal::scalar_add_op<Scalar>, const Derived> operator+ ( const Scalar &  scalar) const [inline]
Returns:
an expression of the coefficient-wise < operator of *this and other

Example:

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

Output:

1
0
0
See also:
all(), any(), operator>(), operator<=()
Returns:
an expression of the coefficient-wise <= operator of *this and other

Example:

Array3d v(1,2,3), w(3,2,1);
cout << (v<=w) << endl;

Output:

1
1
0
See also:
all(), any(), operator>=(), operator<()
Returns:
an expression of the coefficient-wise > operator of *this and other

Example:

Array3d v(1,2,3), w(3,2,1);
cout << (v>w) << endl;

Output:

0
0
1
See also:
all(), any(), operator>=(), operator<()
Returns:
an expression of the coefficient-wise >= operator of *this and other

Example:

Array3d v(1,2,3), w(3,2,1);
cout << (v>=w) << endl;

Output:

0
1
1
See also:
all(), any(), operator>(), operator<=()
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:

Array3d v(1,2,3), w(3,2,1);
cout << (v==w) << endl;

Output:

0
1
0
See also:
all(), any(), isApprox(), isMuchSmallerThan()
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:

Array3d v(1,2,3), w(3,2,1);
cout << (v!=w) << endl;

Output:

1
0
1
See also:
all(), any(), isApprox(), isMuchSmallerThan()
Returns:
an expression of *this with each coeff incremented by the constant scalar

Example:

Array3d v(1,2,3);
cout << v+5 << endl;

Output:

6
7
8

friend const CwiseUnaryOp<internal::scalar_add_op<Scalar>, const Derived> operator+ ( const Scalar &  scalar,
const EIGEN_CURRENT_STORAGE_BASE_CLASS< Derived > &  other 
) [inline]
const CwiseUnaryOp<internal::scalar_add_op<Scalar>, const Derived> operator- ( const Scalar &  scalar) const [inline]
Returns:
an expression of *this with each coeff decremented by the constant scalar

Example:

Array3d v(1,2,3);
cout << v-5 << endl;

Output:

-4
-3
-2

) [inline]
const CwiseBinaryOp<internal::scalar_quotient_op<Scalar>, const Derived, const OtherDerived> operator/ ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other) const [inline]
Returns:
an expression of the coefficient wise quotient of *this and other

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 || 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:

1
0
1
