There are a number of submissions on the File Exchange that helps you with this:

Have you tried the matlab-diagrams package? I encounter a problem when I try that. I found all the parameters like ' diagrams.cylinder_line(c1, c2, LineWidth=8, color=diagrams.colors.blue) ' can not be read by matlab. 'LineWidth=8, color=diagrams.colors.blue' should be ' 'LineWidth',8, 'color',diagrams.colors.blue '. Did I miss something?

No, I think I used one, or both, of the other two. Did they help solve your issue?
