Hey guys,
I use Matlab Online and it is currently (18th of august 2016) very slow, almost unusable. If I wish to save my function, I need to wait 15 minutes for it, executing code takes ages, even if it is a simple size(someSmallVector). I know that Matlab Online is slower than the normal version but it was never so slow. Is there anybody out there experiencing the same issues?
Regards, Fred

the executing time is very unstable. Also if you execute
t=bench
you would notice that the performance could vary a lot in a day, it could be cause by huge amount of user trying to execute their code at matlab online

I've been using Matlab online for a Coursera class and it is very slow. It takes about two minutes to log on, and then it may take another five or six minutes for my files to appear. It's so painful.
When I finally do get my files, the (short, simple) programs run very slowly. If I type '2+3' in the command window it may take a long time to run. Often it is unresponsive.
Not real impressed with Matlab online...

I was bringing this post to the attention of MathWorks IT yesterday. They investigated it and could not find something out of the ordinary, nor were there other customer reports.

i'm currently not even able to load a session ... prior to this I was able to run a script but the site Matlab's session would "end" before the script was done processing ...

I download Octave because of this same reason but then my programming assignments are not getting submitted. "Refused to connect", "Grader sent no response" is the error. Could you help?
