I updated the example code,
you should be plotting this

plot(1:N,FPxx)

or in your case

plot(1:N,mPxxl)

MF is used to plot the Filterbank
i.e.
plot(MF,Filter)

Excellent,
Could do with some more information regarding its use.

Hey guys,
I appreciate all the comments etc.
But i don't have the time to fix these corrections. Its open source so feel free to change it and reuse it yourself.

Carsten Allefeld has made some modifications that fix the normalisation problem. Except in the case of the type 5 distribution.

The sizeOut error has also been fixed.

add this at line 164

p = p/sigma;

just after
p = pearson4pdf(X,m,nu,a,lambda);

it seems the the pdfs are off by this factor

% You need to normalise the histogram properly
[Y,X] = hist(pearsrnd(m{:},100000,1),100)
dX = diff(X)
% Forgot to include this line
dX = dX(1)
bar(X,Y/(sum(Y)*dX))
hold on;
plot(-6:0.01:6,pearspdf(-6:0.01:6,m{:}),'r')

Hi Pierce Brady

Why did you choose f= 512 in
[Pxx,F] = periodogram(x,[],512,Fs);

i am getting

Error using plot
Vectors must be the same lengths.

Error in speechtrial (line 116)
plot(MF,mPxxl);

please help me . How can i resolve this error

Thank you

Dear all
I need to apply Pearson type 5 distribution
to number data following code includes all types how can i extract just type 5?

17 Mar 2012 melfilter generates a mel filter bank for a given frequency vector Author: Pierce Brady Pawel

Sorry Pierce, but I can't plot the signal in the way you exampled it. The dimensions of matrices aren't equal. After filtering my signal with mel bank I get a new signal with length set by the number of filters in the bank, however frequencies vector is much bigger. Do I make something wrong or shall the filtration be done differently? Thanks a lot. Pawel.
