Detailed Description

template<class Basis>
class gtsam::FitBasis< Basis >

Class that does regression via least squares Example usage: size_t N = 3; auto fit = FitBasis<Chebyshev2>(data_points, noise_model, N); Vector coefficients = fit.parameters();

where data_points are a map from x to y values indicating a function mapping at specific points, noise_model is the gaussian noise model, and N is the degree of the polynomial basis used to fit the function.
