It has made mention of Graphviz when I read paper about Bayesian networks. I have no idea about this. It takes me a long time to learn it. And now I make a list for my installing Graphviz with MATLAB.

Please download these packages to your computer refer to [1], like GraphViz program, MATLAB to AT&T GraphViz program and MESHPART toolbox. [1] gives the hyperlinks  to these packages. Then start by installing GraphViz on our computer.

If these all be done, we should add the target directory to MATLAB path, give my examples:

cd D:/SIAT/bayes/GraphViz2Mat1.2

pwd

addpath(genpath(fullfile(pwd, 'GraphViz2Mat1.2')));

savepath % save GraphViz2Mat1.2’s target directory to MATLAB path.

cd D:/SIAT/bayes/meshpartdist/meshpart

pwd

addpath(genpath(fullfile(pwd, 'meshpart')));

savepath % save MESHPART’s target directory to MATLAB path.

You have also not ready to start this, before you modify those files, refer to [2]

First, in dot_to_graph.m change (from line 92)

[node_pos] = sscanf(line(pos_pos:length(line)), ' pos = "%d,%d"')';

x(lst_node) = node_pos(1);

y(lst_node) = node_pos(2);

into

[node_pos] =sscanf(line(pos_pos:length(line)), ' pos = "%f,%f"',2)';

x(lst_node) = round(node_pos(1));

y(lst_node) = round(node_pos(2));

Second, in function draw_dot.m change line 43

labels = names(lbl_ndx);

into

labels = cellstr(num2str(num_names(lbl_ndx)'));

At last you can run the examples in [3]

 

Best wishes, good luck!

PS, give some pictures on my computer
