ValueError: MATLAB failed to start on Mac #233
Description
Hey,
I run your code
from pymatbridge import Matlab
mlab = Matlab()
and then I want to start matlab using
mlab.start()
I get following problem:
Starting MATLAB on ZMQ socket ipc:///tmp/pymatbridge-94df9da7-4b0a-4b45-91b4-c3364735f612
Send 'exit' command to kill the server
............................................................MATLAB session timed out after 60 seconds
ValueError Traceback (most recent call last)
in ()
----> 1 mlab.start()
/Applications/anaconda/lib/python2.7/site-packages/pymatbridge/pymatbridge.pyc in start(self)
223 return self
224 else:
--> 225 raise ValueError("%s failed to start" % self._program_name())
226
227 def _response(self, **kwargs):
ValueError: MATLAB failed to start
If I run the command
~/Applications/MATLAB_R2014b/bin/matlab
the terminal tells me that there is no such file. How can I solve this problem?

Excuse the naive question: do you have Matlab installed? Where is it
installed. Also -- what operating system are you running this on?
If you are on a mac with Matlab 2014b installed (it appears like you might
be), what happens when you type the following in the terminal?
(without the leading tilde)

Sure, I have it installed and I can open it manually (just checked it again).
I am running Yosemite, and usually matlab needs a very long time to start.
So maybe there is a problem with those 60 seconds?
Just typing
/Applications/MATLAB_R2014b/bin/matlab
into the terminal gives me the same as with the tilde.
If I just type
/Applications
I get the answer that it is a directory.

Where is Matlab installed on your machine? (e.g.,
"/Applications/MATLAB_R2014b")?
When you say "gives me the same as with the tilde", what exactly do you
mean? What is the error message you see?

After typing
/Applications/MATLAB_R2014b/bin/matlab
and
~/Applications/MATLAB_R2014b/bin/matlab
I get the same error:
-bash: /Applications/MATLAB_R2014b/bin/matlab: No such file or directory
and
-bash: /Users/jakobschwerter/Applications/MATLAB_R2014b/bin/matlab: No such file or directory
It is installed at "/Programme/MATLAB_R2014b", but using "Programme" did not worked neither and I dont even find the directory "/Programme" so that's why I continued with "/Applications".
I found in another Issue of your's that one user just had to include some PATH, but I don't know what he actually did.

You need to to find the Matlab binary that when called from the terminal starts Matlab. It's typically in a folder such as
/Applications/MATLAB_R2014b/bin/matlab, but you'll have to find where exactly it is on your machine.jaschwer commentedon Mar 27, 2016
I can open matlab witht the following lines:
/Applications/MATLAB_R2016a.app/bin/matlabApplications/MATLAB_R2016a.app/Contents/MacOS/StartMatlabbut not without the ".app"

Great! Does everything work for you now? I think you should pass the first of these strings (
...bin/matlab) as theexecutablekey-word argument to theMatlabobject.jaschwer commentedon Mar 27, 2016
Unfortunately not, sorry.
I used
mlab = Matlab(executable='/Applications/MATLAB_R2016a.app/bin/matlab')mlab.start()and in the backgroup it opens matlab (the icon comes up in my dashboard), but I still get following error:
--> 225 raise ValueError("%s failed to start" % self._program_name())

Could you please copy all the output you get?
