This is an often repeated question, and the last time I remember it being
asked, someone pointed out that the matlab *.fig files are actually *.mat
files (haven't personally confirmed this). This could provide a way
forward if someone wanted to do the leg-work to make a stand-alone module
to achieve this.
On a related note, it looks like we are going to have a beta version of a
pickling solution available in the upcoming release.
Cheers!

Hi all,
is it possible to store figures generated with matplotlib as Matlab files ?
Cheers,
 Nils

My take on this.
https://github.com/matplotlib/matplotlib/pull/1169
And, tight_layout seem to work okay with this change.

Thanks, sounds good just wanted to know if possible now. I will use
something else.
Cheers

This is a bug, or rather one of the ways in which tight_layout is 
limited. twinx and twiny probably will need to return SubplotBase 
instances if their parent is a SubplotBase instance. I don't 
immediately see a quick and easy way to do this. I filed a ticket:

For example running this code and then fig.tight_layout(). The second axis
isn't recognized. Is there a way to add it to the tight_layout spec or a
better method.
out = ones(200)
fign = 52
h, w = freqz(out)
fig = figure(fign)
semilogy(h,abs(w)/abs(max(w)), 'b', label='Mag')
ylim(0.01,1.2)
ylabel('Amplitude (db)', color='b')
xlabel('Frequency (rad/sample)')
ax = fig.gca()
ax2 = ax.twinx()
angles = unwrap(angle(w))
plot(h, angles, 'g')
ylabel('Phase (rads)', color='g')
Cheers,
Jeff

I didn't try out your code, but I created a solution here (complete code) :
