f = figure;
f.Color = 'w';
f.Units = 'normalized';
f.Position = [.1 .2 .8 .5];

M1 = readmatrix('https://www.mathworks.com/matlabcentral/answers/uploaded_files/604555/x%20articolo.xlsx', ...
    'range', 'B3:V14');
M2 = readmatrix('https://www.mathworks.com/matlabcentral/answers/uploaded_files/604555/x%20articolo.xlsx', ...
    'range', 'AA3:AI14');
M3 = readmatrix('https://www.mathworks.com/matlabcentral/answers/uploaded_files/604555/x%20articolo.xlsx', ...
    'range', 'AL3:AU20');

contour(M1);
