Things were working properly till yesterday. I am unable to find what changed.

The following different steps didnt resolve the issue:

1) restoredefaultpath

2) reset(gca)

3) reinstall matlab (I am using networked version in Institute)

I have the same problem. In fact, just moving the mouse over the plot causes the error for me. I'm using Matlab 2019a Update 5 on a MacOS Mojave device, and I'm using an external (non-retina) display in junction with the (retina) diplay on my laptop.

My suggestion is to rename all the files in current folder to something else and see if the problem persists. It could be resolved if an m file in the current folder is conflicting with matlab inbuilt functions.

Answer 1

[Sajith Kk]

I found the solution. It was happening only when the current folder was in a particular folder in which there was a m-file named 'settings.m'. Probably there was a conflict between this file and a file related to plot function. It was resolved when I renamed the file to something else.

I just updated to version 2019b, and that version freaks out even more when there is a file called "settings.m" in an included folder. This is rather embarassing. Please Matlab, let your users name their files whatever they want.

I have had the same problem with settings.m, my solutions was to rename the file.

In the future, i am checking the doc for commands with similar name. This Problem could even happen with similar variables names.

I met this problem when im plotting the training-progress of deep learning toolbox, this solution solved my problem perfectly, Thank u !!!

Hello, which folder do you want to change the settings.m file in, I don't understand it, it's driving me crazy, I hope you can answer it for me!

[ed]

The point is that if your project contains a file called 'settings.m' (or some other filename which conflicts with a built in matlab file) you may have this problem. Try renaming files in your project with rather generic filenames to use more custom names.
