% AUSGABE MATLAB code for Ausgabe.fig
%      AUSGABE, by itself, creates a new AUSGABE or raises the existing
%      singleton*.
%
%      H = AUSGABE returns the handle to a new AUSGABE or the handle to
%      the existing singleton*.
%
%      AUSGABE('CALLBACK',hObject,eventData,handles,...) calls the local

%
%      AUSGABE('Property','Value',...) creates a new AUSGABE or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Ausgabe_OpeningFcn gets called.  An

Why did you post this wall of unformated code? Do you expect anyone to actually read it?

Lucky for you the error message tells us everything we need to know: the nanmean function call returns an error.

If you have a look at the documentation, you will see that nanmean is no longer recommended since R2020b. Replace the call with mean using the 'omitnan' flag.

KL=mean(RR','omitnan');

Hello Diana,

‘nanmean’ is a part of the "Statistics and Machine Learning Toolbox", which I believe you do not have, and which is why you get the error. Additionally the use of ‘nanmean()’ is not recommended anymore. Use ‘mean’ with ‘omitnan’ option to perform the same operation.

Replace all instances of ‘nanmean’ with ‘mean’ as:

mean(sampleData, 'omitnan');

Please refer to the following documentations for more details:

1. ‘nanmean’ - https://www.mathworks.com/help/stats/nanmean.html
2. ‘mean’ - https://www.mathworks.com/help/matlab/ref/mean.html

I hope it helps you query!

Hi @Diana Gaier

Well, to better help you - better is not to paste the whole huge M file code, but to attach is as a file.

Anyhow - few issues:

• This is a 'M' file created with guide. Please attach both M + fig file
• In the error @ the end of your code pasted above :
• Error in Ausgabe>pushbutton4_Callback (line 675)
• this callback does not exist, in the code above (attaching the whole file, will probably consists of this callback)

Specifically - this error means that ou call a function that is not knows in the current context

You call nanmean from pushbutton4_Callback.

Where is this function defined? Looks like it is not under the PATH.

You can debug the file onl line 675 and when reaching this line (on a breakpoint) - type on the command line:

which namean

If Matlab idetifies this function - it will return the absolute path to it.

Otherwise - find where it is defined and "enable" it using one of the next ways:

1. Add the path to nanmean to Matlab's PATH
2. Put nanmean.m in the path where Ausgabe.m is located
3. Add this function to Ausgabe.m file

Good luck!
