it's a 42k X 2 vector, I'm having a rather difficult time using octave, sometimes it gets the data from the audio file and sometimes it's just rows of zeros.
I tried your command to no avail
Did you try

Dear Esteemed Volunteers.
I have a question about incorporating a piece of code into my project.
I have found this piece of code online
Fs = 1000; t = 0:1/Fs:1-1/Fs; x = cos(2*pi*100*t)+randn(size(t))
; [Pxx,F] = periodogram(x,,length(x),Fs) ; plot(F,10*log10(Pxx))and I would like to use the wavread command and use that signal in place of the Fs,t and x. So, I wrote this bit of code
[y, fs]= wavread('song1.wav');NFFT=input("Choose a fraze size of either 128, 256 and 512. ");[Pxx,F] = periodogram(y,,NFFT,fs);
But I am sad to report this it is not working, and that I am receiving this error⹏፥error: periodogram: X must be a real or complex vector
what is the dimension of y?
It might have 2 col.
If it does then try y(:,1)
If you can help me I would appreciate it immensely
