Hi,

I recently installed MATLAB 2018b onto a new Windows 10 machine. Running an old .m file, I now see an error when calling the "errorbar" function:

Undefined variable "matlab" or class "matlab.graphics.chart.internal.checkpvpairs".

Error in errorbar>parseargs (line 255)

msg = matlab.graphics.chart.internal.checkpvpairs(pvpairs,linestyleerror);

Error in errorbar (line 61)

[pvpairs,args,nargs,msg,orientation] = parseargs(args);

I can't find a similar error occuring elsewhere online. Has anyone seen this error before?

Thanks,

David

I'm having the same problem, but restoring matlab path doesn't fix it.

@Walter Robersonshould I make a seperate issue?

Reinstall.

In cases where restoredefaultpath provides relief, then afterwards

savepath

or else go into pathtool and click on save
