Good morning,
I face an issue while displaying simple matrix using such a script:
N=4096; a=ones(N,N);
figure(); mesh(a)
Matlab take minutes to display the surface and once dislayed it takes some more minutes to get out a frozen state.
I am not an expert at all but it seems to me it can be connected to the Graphical processor.
mine is NVIDI Quadro P1000, I don"t know whether this is a well sized one.
Many thanks for your feedback
Frederic

I was running in MATLAB R2020b.

what I know now:
matlab2020b + mesh(4096) + Imac2012 = few sec
matlab2012 + mesh(4096) + laptop DELL Precision5530 = few sec
matlab2018b + mesh(4096) + laptop DELL Precision5530 = few minutes
matlab2019a + imagesc(4096) + laptop HP ProBook (very basic) = few sec
I just installed matlab2020b, and now:
matlab2020a + imagesc(4096) + laptop DELL Precision5530 = few sec
and back to matlab2018b:why
matlab2018b + imagesc(4096) + laptop DELL Precision5530 = few sec
Conclusion:
my pb is solved but I don't understand how.
(By the way it is not specific to my laptop since a colleague faces the same issue)
