numpy to matlab interface with mlabwrap
Question: I am looking for a simple way to visualize some of my data in numpy, and I
discovered the `mlabwrap` package which looks really promising. I am trying to
create a simple plot with the ability to be updated as the data changes.

Here is the matlab code that I am trying to duplicate

    
    
    >> h = plot([1,2,3], [1,2,3], '-o');
    >> set(h, 'XData', [0,0,0]);
    >> drawnow();
    

to python

    
    
    >> from mlabwrap import mlab
    >> h = mlab.plot([1,2,3], [1,2,3], '-o')
    >> mlab.set(h, 'XData', [0,0,0])
    >> mlab.drawnow();
    

However, the second to last command fails with an error message

    
    
    error: One or more output arguments not assigned during call to "set".
    

Any suggestions on how to fix this?


Answer: Maybe mlab is mad that you're not saving matlab's return value for that set()
call...

I don't have this installed, what does `someval = mlab.set(h,'XData')` give?

edit: you could also try using nout... `mlab.set(h,'XData',[0,0,0],nout=0)`
