I guess the problem is that the Matlab line "print -dpng testplot.png"
is correctly writing the plot to testplot.png, as you want, but then
org-mode is overwriting that file because of the ":file testplot.png".
I would try deleting ":file testplot.png".
The meaning of ":results output" may be a bit language-dependent - I
don't know org-mode well enough to be sure about that yet - but in
general I would expect it to consist of the standard output of those
commands. So, for example, if you type "print -dpng testplot.png" and
Matlab responds with "Generated 'testplot.png'", I would expect
":results output" to contain "Generated 'testplot.png'", not the PNG data.
