在 MATLAB Online 中打开

Filename ='P.csv';
data = csvread(Filename);
xmin = min(data(:, 1));
xmax = max(data(:, 1));
ymin = min(data(:, 2));
ymax = max(data(:, 2));
figure;
scatter(data(:, 1),data(:, 2),15,"filled");
    xlabel('X - Axis')
    ylabel('Y - Axis')
hold on;
rectangle('Position',[xmin ymin xmax-xmin ymax-ymin],'EdgeColor','r',...
    'LineWidth',1.2)
% Calculating length and strips
Polygon_Length = max(xmax-xmin,ymax-ymin);
Userdefined_Strip_Width = 1;
strips = Polygon_Length/Userdefined_Strip_Width;
% Dividing rectangle into multiple strips
for i = 1:strips
    x1= xmin + (i*Userdefined_Strip_Width);
    y1= ymax;
    x2= xmin + (i*Userdefined_Strip_Width);
    y2= ymin;
    plot([x1 x2], [y1 y2])
end
