How to Compile an Application with the "pspectrum" function?

I am trying to compile an application that uses the "pspectrum" function (I think it is from the Signal Processing toolbox), but I am having trouble with including the right files in the compiler. I have attached a screenshot of my compiler and the error message I am getting from my compiled application. Are there any other / different files that I should be including in the compiler, or are there other issues that need to be addressed here as well?

Tried that before but was getting the same error. I moved that function to our file path and added it to the compiler, and got a new error message that I attached to this message.

Does anyone know where "signalanalyzer.internal.Spectrogram" is defined? I cannot find it in the functions that I'm looking at in the MATLAB toolbox folders.

My latest update in compiling is attached. I compiled the pspectrum.m and signalAnalyzer.m files and the "signal" toolbox folder. Now I need to include "coder", which I was unable to do by compiling with the entire "coder" toolbox folder.

After speaking with a MATLAB representative, we found that the issue is that the pspectrum function cannot be compiled with the MATLAB Application Compiler in versions before 2019a.

  • The signalAnalyzer app is not compilable.
  • You shouldn't have to do anything to compile pspectrum, it should just work. Do you have a license for signal processing toolbox checked out at compile time?
  • You may need to run: rehash toolboxcache

The application I am trying to compile references pspectrum so I have been trying to compile with a number of file required to run. The latest error I get when I add the entire signal toolbox folder is the "Undefined variable "coder" or class "coder.internal.isCompiled"." error when I am running the part of my application that uses pspectrum.
