Plot: LoadLibrary failed with error 87

50 views (last 30 days)
I suddenly started to have the error "LoadLibrary failed with error 87: the parameter is incorrect" every time i try to use plot or scatterplot. I tried many way to solve it but no way.
I'm using Windows 8.1 with matlab 2015a and I started to have the same problem also with Matlab 2014a.
Please help.

I solved the problem on my own. For those having a ati graphic card, the problem is related (at least in my case) to the file "atig6pxx.dll" in windir/system32 (Our you can search for it).
I've found the solution at this link and solved the problem by renaming "atig6pxx.dll" into "atig6pxx.dll.bak" (you need to change the extention of the file.)

I am having this issue while i am doing remote desktop connection. Do i need to change the name to atig6pxx.dll.bak on my own home computer or on remote office computer?

function p = prob_table(x)
p = hist(x, 1:max(x))/numel(x);
