CwiseUnaryOp< UnaryOp, XprType > Class Template Reference

Detailed Description

template<typename UnaryOp, typename XprType>
class Eigen::CwiseUnaryOp< UnaryOp, XprType >

Generic expression where a coefficient-wise unary operator is applied to an expression.

Parameters

UnaryOp	template functor implementing the operator
XprType	the type of the expression to which we are applying the unary operator

This class represents an expression where a unary operator is applied to an expression. It is the return type of all operations taking exactly 1 input expression, regardless of the presence of other inputs such as scalars. For example, the operator* in the expression 3*matrix is considered unary, because only the right-hand side is an expression, and its return type is a specialization of CwiseUnaryOp.

Most of the time, this is the only way that it is used, so you typically don't have to name CwiseUnaryOp types explicitly.
