How can I change the Default figure properties? In 2017a DataAspectRatioMode and PlotBoxAspectRatioMode were set to Auto by default. In 2017b it is by default set to Manual. I want to change it to Auto for all figures, not having to change it for each figure individually. There must be a way...

So this is what I tried:
set(groot,'DefaultAxesDataAspectRatioMode','auto')
set(groot,'DefaultAxesPlotBoxAspectRatioMode','auto')
and
set(0,'DefaultAxesDataAspectRatioMode','auto')
set(0,'DefaultAxesPlotBoxAspectRatioMode','auto')
But nevertheless when I plot a figure these properties are still on 'manual' as checked in the property Editor; even though the properties are set to 'auto' which I checked with
get(groot,...

Post your full get(groot) line. And a snippet of your plotting code.

I implement the get-command with
get(groot,'defaultAxesPlotboxAspectRatioMode')
get(groot,'defaultAxesDataAspectRatioMode')
And the response is ans = 'auto'
The plot-code is something like:
figure();
pdemesh(p,e,t)
And I have this problem since I changed from 2017a to 2017b.
Thanks a lot for helping me!

Any groot defaults are just that: defaults. If a value is not overridden by the user, it remains default. Otherwise, the default value is ignored.
The pdemesh function calls either pdeplot or pdeplot3D to do the legwork. Both of these then have axis equal in them. Calling axis equal (or likely any input to the axis function other than auto) changes the aspect ratio, thereby negating the default values, and setting mode to manual.

Not sure why the behavior is different in R2017a and R2017b, but I did confirm I'm seeing the same thing you describe.

Because axis equal is called in pdeplot R2017b, but not in R2017a. Thank you so much for your help!
