Detailed Description

template<typename T>
struct roboptim::detail::const_ref< T >

Return the proper const reference type of a given type.

For instance:

• const_ref<float>::value_t == const float&
• const_ref<argument_t>::value_t == const_argument_ref

This returns a const Eigen::Ref for dense Eigen matrices, else a simple const reference.

Note: this currently does not cover all cases (e.g. sparse vectors), but should work for argument_t/vector_t (dense vectors).

Template Parameters

T

type.
