Eigen::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.

Template Parameters:
UnaryOptemplate functor implementing the operator
XprTypethe 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.
