You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ContourFitting.m
    path of file: ./repos/mexopencv/opencv_contrib/+cv
    
    the code of the file until where you have to start completion: classdef ContourFitting < handle
    %CONTOURFITTING  Contour Fitting algorithm using Fourier descriptors
    %
    % Contour fitting matches two contours `z_a` and `z_b` minimizing distance
    % `d(z_a, z_b) = sum_n (a_n - s * b_n * exp(j * (n * alpha + phi)))^2`
    % where `a_n` and `b_n` are Fourier descriptors of `z_a` and `z_b` and `s`
    % is a scaling factor and `phi` is angle rotation and `alpha` is starting
    % point factor adjustement.

            %     dst = cv.ContourFitting.fourierDescriptor(src)

            %
            % ## Input
            % * __src__ input contour, vector of 2D points stored in numeric
            %   array Nx2/Nx1x2/1xNx2 or cell array of 2-element vectors
            %   `{[x,y], ...}`.
            %
            % ## Output
            % * __dst__ 2-channel array of type `single` and length `NumElt`.
            %
            % ## Options
            % * __NumElt__ number of rows in `dst` or cv.getOptimalDFTSize
            %   rows if `NumElt=-1`. default -1
            % * __NumFD__ number of FD to return in `dst`,
            %   `dst = [FD(1...NumFD/2) FD(NumFD/2-NumElt+1...:NumElt)]`.
            %   default -1 (return all of FD as is).
            %
