Detailed Description
template<typename T, typename... Args>
class gtsam::ExpressionFactorN< T, Args >
N-ary variadic template for ExpressionFactor meant as a base class for N-ary factors. Enforces an 'expression' method with N keys. Derived class (an N-factor!) needs to call 'initialize'.
Does not provide backward compatible 'evaluateError'.
- Template Parameters
-
T Type for measurements. The rest of template arguments are types for the N key-indexed Values.
