is poctave function working ?

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.

Restart the PC : the universal windows solution !

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.
