Detailed Description

template<typename Derived>
class MatrixFunctionReturnValue< Derived >

Proxy for the matrix function of some matrix (expression).

Template Parameters:

Derived

Type of the argument to the matrix function.

This class holds the argument to the matrix function until it is assigned or evaluated for some other reason (so the argument should not be changed in the meantime). It is the return type of matrixBase::matrixFunction() and related functions and most of the time this is the only way it is used.
