cast()

template<typename NewType >

EIGEN_DEVICE_FUNC CastXpr<NewType>::Type cast

(

)

const

Returns

an expression of *this with the Scalar type casted to NewScalar.

The template parameter NewScalar is the type we are casting the scalars to.

conjugate()

EIGEN_DEVICE_FUNC ConjugateReturnType conjugate ( ) const

inline

Returns

an expression of the complex conjugate of *this.

inline

Returns

an read-only expression of the imaginary part of *this.

operator-()

EIGEN_DEVICE_FUNC const NegativeReturnType operator- ( ) const

inline

Returns

an expression of the opposite of *this

Definition at line 45 of file CommonCwiseUnaryOps.h.

real()

EIGEN_DEVICE_FUNC RealReturnType real ( ) const

inline

Returns

a read-only expression of the real part of *this.

unaryExpr()

template<typename CustomUnaryOp >

EIGEN_DEVICE_FUNC const CwiseUnaryOp<CustomUnaryOp, const Derived> unaryExpr ( const CustomUnaryOp &  func = CustomUnaryOp() ) const

inline

Apply a unary operator coefficient-wise.

Parameters

[in]

func

Functor implementing the unary operator

Template Parameters

CustomUnaryOp

Type of func

Returns

An expression of a custom coefficient-wise unary operator func of *this

The function ptr_fun() from the C++ standard library can be used to make functors out of normal functions.

Example:

Output:

Genuine functors allow for more possibilities, for instance it may contain a state.

Example:

Output:

unaryViewExpr()

template<typename CustomViewOp >

EIGEN_DEVICE_FUNC const CwiseUnaryView<CustomViewOp, const Derived> unaryViewExpr ( const CustomViewOp &  func = CustomViewOp() ) const

inline

Returns

an expression of a custom coefficient-wise unary operator func of *this

The template parameter CustomUnaryOp is the type of the functor of the custom unary operator.

Example:

Output:
