Hello guys,
I have a problem with MATLAB App Designer. I've written a code that smooths data using 'Smooth response data' in the main MATLAB software. However, when I use it in App Designer, App Designer recognizes the smooth function as 'Backward recursion of diffuse state-space models'. I don't know how to solve this problem.
I would be very thankful if you could help me.

Hey Mojtaba
It appears that the "smooth" function you were using is being overshadowed by another function with the same name. Since the function you intend to use would be a basic function, you can easily find alternatives for it.
  1. You could use the "smoothdata" function to achieve the same functionality. You can refer to the following documentation: https://www.mathworks.com/help/matlab/ref/smoothdata.html
  2. You can also find several implementations of the "smooth" function over the File Exchange Submissions. Check out the following submission for smoothing 1D data: https://www.mathworks.com/matlabcentral/fileexchange/66099-smoothing-1d-data-by-moving-different-filter-shapes?s_tid=srchtitle
  3. For adding a custom implementation of data smoothing, please have a look at the following documentation: https://in.mathworks.com/help/matlab/data_analysis/data-smoothing-and-outlier-detection.html?s_tid=answers_rc2-1_p4_MLT
I hope this helps!

Thank you so much for your help. I tried to use smoothdata() but did not work correctly for me.

What issue were you facing with smoothdata() ?
The smooth() function can be easily implemented by a moving average filter and there would be various implementations available to choose from FEX submissions. If not, could you share the exact issue you are facing? Maybe you could attach a part of your code so that I could reproduce it at my end.
