When I try to open Matlab online it just gets stuck in the loading screen. It has been doing this since yesterday when I tried to use strcmp in a for loop of a file with like 2000 lines.

I'm getting the same. Problem. They say removing the files with the.asv extension clears pending sessions but it's not working. Is it a server problem and will it be resolved automatically? HELP

  1. The line of code given in the error message does not occur in the code you posted. The code you posted does not have a file path in imread()
  2. The line of code that gives the error message is executing on MATLAB Online, which executes on Linux, but the line of code attempts to use MS Windows path syntax. Your MATLAB Online system has no concept of a C: disk and uses forward slash / rather than backwards slash \ to separate directory parts.

Matlab online is not working. Not only in my computer. I think It is a general problem.
Support service could confirm general problems?

I have the same problem. I was running my code in Matlab Online when the compiler got stuck. Do I have to contact with tech support?

Yea support is useless. They just need to end your hung up session but their support doesn't use logic or something because you're going to have to hold their hand to do their job.

My name is Ovanes Petrosian. I am having the same problem right now. Tomorrow I will have a conference, but now I cannot run my Matlab code to generate figures etc. Yesterday I was loading some huge symbolic formulas and now it is just not working.
I cannot run my Matlab code When I even start some simle thing like open a several .m file it is stuck etc.
I need help right now or I will just switch to something like Mathematica or Python.
Best regards, Ovanes.

I am facing the same issue. It's saying "Please wait while Matlab online stablishes a connection" for the past 4 hours. Any solutions to this?

Try again. The people in the know said yesterday: "There was a router failure last night, MATLAB Online was running normally at about 4am."
Call them if you continue to not be able to access it.

When I try to click the 'Open MATLAB Online' button, it shows the loading screen and then goes back to the screen with the 'Open MATLAB Online' button, but Matlab does not open. Tried with Chrome and Edge and both experienced the same problem.

Are you still experiencing this difficulty?
I just tried it and it worked for me.

There was an incident on December 4th according to the Application Status page but it indicates MATLAB Online should be operating normally. Please contact Technical Support and work with the support staff to determine the cause of this problem.
