Detailed Description

Effectively reduce the number of arguments taken by fun.

For each position not listed in vary the value from the corresponding position in fix will be substituted in at call time.

Member Function Documentation

double NC::Fitter::FixVars::EvalAtEx (  const CoordNDim &  r,
CoordNDim *  ret
)  const [virtual]
 

Find the value of the function and return additional information.

Parameters:
r Coordinate at which to evaluate the function
[out] ret Return additional information. By convention, the true underlying coordinates evaluated.
Returns:
Value of the function at the point r
Implementations must be prepared for ret to be null

Todo:
Rename to just EvalAt

Implements NC::Fitter::ICallableND.
