I want to know how can I make a graphic (see below). How can I connect the numbers from the first column the numbers with the second columns. And I need to make the lines connecting the points become thicker to be more links. I make this command for calc %.

maxdata = max(data(:,1:2));
counts = accumarray(data(:,1:2), 1, [maxdata(1,1), maxdata(1,2)]);
for i = 1:maxdata(1,1)
    for j = 1:maxdata(1,2)
        link(i,j) = counts(i,j)
    end
end
    somalink = sum(link(:));
    porcentagem = link./somalink.*100;

No need for loops. And note, when you do use loops, try to avoid using i and j as variable names--they're the imaginary unit. Overwriting i and j rarely causes a problem, but when it does it can be tough to debug.

A = [9  1  2  4;
2  1  2;
2  2  6;
1  3  3;
4  1  3;
2  2  8;
1  1  5;
1  2  8;
1  3  8;
3  2  9;
4  2  6;
2  1  1;
4  3  9;
2  3  9;
5  2  5;
2  2  1;
3  3  8;
3  1  1;
2  3  2;
5  2  1;
3  3  2;
5  1  3;
3  2  9;
5  3  5;
3  2  7];
figure
plot([1 2],A(:,1:2),'ko-','markersize',20,'linewidth',2,'markerfacecolor','w')
axis([0 3 0 11])
axis off

From the first sentence, are you saying that one node and another node is connected N times, then you'd like a line connecting them to be N pixels wide, whereas if it's just connected once, the line is 1 pixel wide? Yes. It is

OK, your new/edited graphic above helps explain the thickness question. Note the 'linewidth' option in plot. You'll have to plot the lines one at a time, varying the linewidth parameter for each line segment.

Now, what about the line length question? Your answer seems to have been cut off.
