Is it possible conserve the workspace between two different calls of the function mlab.run_code() for instance?

Hi, I need to generate dynamically a matlab script from python and I would like to use the bridge to send execute my dynamic scripts in Mlab, but I would like to conserve the workspace between two Mlab calls. Is this possible?

Sorry for the delay in reply. The answer is yes.

For example, once you have started an instance of the bridge, the following should work:

mlab.run_code("a=1")
# More code doing something else
mlab.run_code("b=a+1") # This is what you meant, right?

Thank you! I found it out! But I cannot use it anyway because when I need
to use big matrices in MATLAB I have an error in the open_page method! I
have a badrequest error! I will explain you a bit so you can try to fix it!
I have to make a script that from python query MATLAB and ask to export
some information! If you try to send a request with run_code where inside
you call a MATLAB script that contains for example a plot with a pcolor
(rand(1000,1000)) you will have am error in open_page method! A bad request
even if the MATLAB continue and finish the execution of the script request!
After that the pymatbridge is not working and even if you try to connect
again in the same script it will not work properly! Hope to be useful!

Hmm - interesting. Would you mind posting a minimal example of all the code
you ran and caused this issue?

Thanks !

Hi

I made up an example that give me exactly the same error of my script.

If you can let me know some informations when you try it, it will be very
useful!
