Using spectralFlux to plot Flux of a vector

Hi,
I have a waveform in time domain, but it is digitized, so It is basically a vector (yy). How can I plot Flux for it? When I write
flux = spectralFlux(yy,fs);
Error: Undefined function 'spectralFlux' for input arguments of type 'double'.
Seems MATLAB doesn't recognize spectralFlux. I'd appreciate your help at this matter.
Thanks

Sarah,
Which MATLAB release are you working from? This function was introduced to audio Toolbox in R2019a.

It is not at all clear what you want to do, spectral flux is not a term I've heard before - this might be because I'm ignorant, or because you've translated from another language and the exact English term is something else. I'll take a swing anyways...
You might be interested in the spectrogram function. Have a look at the help and documentation for that function.
If I'm way off, you might get better help if you describe what spectral flux is in more detail.
