Hello,
the example 1 given in poctave help :
% EXAMPLE 1:
% Construct a unit-variance white noise input signal sampled at
% 44.1 kHz. To determine the octave spectrum, choose a filter
% order of 8. Visualize the octave spectrum between 120 Hz and
% 20 kHz.
Fs = 44.1E3;
xInp = randn(2^16,1);
poctave(xInp,Fs,'FrequencyLimits',[120 20E3],'FilterOrder',8);
just doesn't work on my computer here you can find the error message is :
Error using bar (line 213)
Data inputs must match the axis configuration. A numeric axis must have numeric data inputs or data inputs which can be converted to
double.
Error in poctave>localplot (line 745)
pObject = bar(centerFreqLabels, PdB);
Error in poctave (line 205)
localplot(P,CF,opts);
Does anyone have an idea of what is wrong ?

hello
according to the line numbers where the errors occured, its seems your poctave version differs from mine (no errors)
I have R2020b update 1
code for poctave :

The code you posted runs correctly in R2021a, since it runs correctly in the online Run feature here that uses it —
Fs = 44.1E3;
xInp = randn(2^16,1);
poctave(xInp,Fs,'FrequencyLimits',[120 20E3],'FilterOrder',8);
My only suggestion is to exit and restart MATLAB, then run the example again to see if the problem persists after that.

That certainly works as well!
All I usually need to do is restart MATLAB in situations like that, although Windows issued updates in the last couple days that might cause problems without restarting.
