How to embed a spectrum analyzer into the GUI created by App Designer

Hello

I'd like to use spectrum anaylzer on my application created using App Designer.

But it is not embedded on my application window.

My codes are as follows :

-----------------------------------------------

function ButtonPushed(app, event)

..........

% % Spectrum Analyzer

spectrum = spectrumAnalyzer('SampleRate', Fs);

spectrum(waveform);

release(spectrum);

----------------------------------------------

Please let me know how to do it.

Thank you.

Hi!

I don't think there is a way to embed spectrum analyzer directly into your app, however there are multiple workarounds, one of them is to calculate power specta using pspectrum function and then use semilogy to plot against frequency.

Let me know if this helps.
