Help on how to use plot::SurfaceSTL

Hi everyone. ^___^ This is my first time posting a question and I apologize if it's a silly one but the command plot::SurfaceSTL has been giving me a massive headache.

I simply just wanted to know how to use this command - I've tried the line below (the format of which was taken from the documentation page for the command):

ServoBracket := plot::SurfaceSTL('ServoBracket.stl');

But that just gave me errors:

Undefined function 'ServoBracket' for input arguments of type 'char'.

So if anyone could shed some light on this situation or provide some basic working code, I'd be extremely grateful! ^___^

Also, since I'm on the topic, could I possibly know what the :: and := do exactly? I can't seem to find any info on them. :(

Thank you for your time.

Best Regards, A.K

If you look at the URL for the documentation, http://www.mathworks.com/help/symbolic/mupad_ref/plot-surfacestl.html notice it includes "mupad_ref". That means it is a routine that is defined directly within the MuPAD programming language.

You can start up a MuPAD notebook from the MATLAB command line by giving the command mupad . You can then run that line of code from there.

Alternately, you can call into MuPAD from the MATLAB command line. You would use something like,

ServoBracket = feval(symengine, 'plot::SurfaceSTL', 'ServoBracket.stl');

Unfortunately I have no information about what happens if you attempt to use a MuPAD plotting command from the MATLAB command line.

Thanks for the reply! ^___^ I gave the code above a try but it came up with the following error:

MuPAD error: Error: First argument: expecting an STL file name. [plot::SurfaceSTL::new]

So then I tried the following:

ServoBracket = evalin (symengine, 'plot::SurfaceSTL("ServoBracket.stl")');

Which didn't return any errors but also didn't do anything. :/ I'm just trying to find some information on how to read plots from MuPAD now ... I'm guessing there wouldn't be any other ways of importing 3D models into MATLAB?
