Returns

an expression of the coefficient-wise power of *this to the given array of exponents.

This function computes the coefficient-wise power.

Example:

Array<double,1,3> x(8,25,3),
                  e(1./3.,0.5,2.);
cout << "[" << x << "]^[" << e << "] = " << x.pow(e) << endl; // using ArrayBase::pow
cout << "[" << x << "]^[" << e << "] = " << pow(x,e) << endl; // using Eigen::pow

template<typename OtherDerived >

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:

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:

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:

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:

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:

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:

See also

all(), any(), isApprox(), isMuchSmallerThan()

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:

zeta()

template<typename DerivedQ >

const CwiseBinaryOp<internal::scalar_zeta_op<Scalar>, const Derived, const DerivedQ> zeta ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< DerivedQ > &  q ) const

inline

Returns

an expression of the coefficient-wise zeta function.

\specialfunctions_module

It returns the Riemann zeta function of two arguments *this and q:

Parameters

q	is the shift, it must be > 0

Note

*this is the exponent, it must be > 1.

This function supports only float and double scalar types. To support other scalar types, the user has to provide implementations of zeta(T,T) for any scalar type T to be supported.

This method is an alias for zeta(*this,q);
