Detailed Description

template<typename T, typename Function>
class UnivariateLinearLsqFitLarge< T, Function >

Linear least-squares fit of data to a function

Use this version for large data sets and when the number of parameters is NOT known at compile time.

Function objects have to conform to a simple interface: (it is a template object in this example, but does not need to be).

template<typename T, typename Tpar, int N> class Poly1D { public: typedef Tpar param_vector_type; typedef T value_type;

// get number of paramters int npar ();

// evaluate at location x for parameter vector p T operator()( const T x, const TPar& p ) const;

// return the n-th basis function evaluated at values in array x MArray<T,1> get_nth_basis( const int n, const MArray<T,1>& x )

// optional static void prettyPrint(ostream& os, const TPar& p); };
