Matlab R2017a very slow

Hi everyone,

I notice today Matlab R2017a is very slow. I am running on windows 10. The task manager shows nothing abnormal. I hit 'Run and Time' and we can see my function 'plot_script_tailsitter' which creates about 15 plots containing about 40'000 data points takes 168 seconds !!! It takes about 2 sec usually.

I do a 'close all' at the beginning of the code: itself takes 32 sec.

Yesterday it worked fine. Does anyone have the same problem ? or any suggestion ?

Thanks,

Romain

p.s. My first suggestion would be to go back to Matlab 2016b...

Hi everyone, I have the same problem. My computer has windows 10 and I've tried Matlab 2017a and 2017b. I thought that maybe was because of the latest Matlab version but I've just installed Matlab 2016b and the problem continues. Does anyone have any idea about why is the problem, and its solution?

Thanks

Similar problem here still unresolved. Please refer to my comment in: Why my Matlab 2017a is so slow for even simple commands?

Try this command...

    opengl('save','software')

Restart matlab.

I have similar problems. A script on Matlab 2016b runs fine (contains significant number of lines to plot). Starting from Matlab 2017 the script is usable due to the plot performance. In Matlab 2019a is still present. The command opengl('save', 'software') does not work for me.

I went back to Matlab 2016. I could not find any solution on the internet ?

I don't want to rewrite my scripts, if possible.

I had my performance problems resolved using R2018b.

I tried the scripts with Matlab 2019a, but the graphics / plotting is still terrible slow.
