Questions about Matlab programming

Hi everyone I have some questions about a matlab .m file i recently downloaded.

it starts like

classdef name < handle
    properties
        svm_type = 's'
        fig;
    running = true;

    plot_area;
    draw_flag = true;
    cont_flag = false;
    lin;
    weight_handle;
    w_arrow = [0.9482 0.8060; 0.8068 0.9482];
inputs;
    %Data - outputs
    outputs;
    %The colors of the data points
    colors;
    %The currently dragged data item
    data_drag;
    %Coordinates of misclassified data
    errors;
    %Error text
    error_disp;
end

methods

    function a = name()
a.lin = LinearClassifier([1 1], @()a.lin_change());
      a.train_method = a.svm_type;
      %The main figure window. Call the layout function on resize
      screen_size = get(0, 'ScreenSize');   
      a.fig = figure('Name', 'SVM Demo', 'Position', [(screen_size(3) - 600) / 2 (screen_size(4) - 450) / 2 600 450], 'MenuBar', 'none',...
        'ResizeFcn', @(varargin)a.do_layout);
....
....
end
end
end

I have never seen this type of programming in matlab, and even though i think i understand it to some level it would be nice if someone could explain me better the basics of this.
