Hi Olivier and list,
at first thanks for the modification of uncell.m!
At the moment I have another problem with the new version:
mirinharmonicity function estimates too much NaN values for several test
songs (the old version estimated a couple of NaNs only at the beginning
of the songs).
Here is my code:
[ih,s,ff] = mirinharmonicity(a,'Frame',4096,'sp',4096,'sp');
res=mirgetdata(ih);
Do you have any idea?
Kind regards,
Igor

Hi Igor,
I finally found time to look at that problem. In fact, mirgetdata was
not preserving the array direction (column vs. row) of unidimensional
cell arrays.
I modified the file uncell.m (cf. enclosed) and it seems to work on
your examples. I will include this fix in update 1.4.1.
All the best,
Olivier

The same situation occurs e.g. for
[ih,s,ff] = mirinharmonicity(a,'Frame',512,'sp',512,'sp');
res1=mirgetdata(ff); res2=mirgetdata(ih);
(comparing res1 and res2) - so this behaviour seems to be
systematically if several outputs are generated?

dimensions in later MIR Toolbox versions Date: Tue, 24 Jul 2012

Hi Olivier and MIR Toolbox list,
I have a question about vector dimensions in the later MIR
Toolboxes. It seems to be that some dimensions have been switched,
but not always consistently. Consider the following code:
a=miraudio(input_file);
f=mirframe(a,'Length',wlength,'sp','Hop',woffset,'sp'); chroma =
mirchromagram(f); [k c]=mirkey(chroma); key=mirgetdata(k);
clarity=mirgetdata(c);
The last version (1.4) returns key as 6878x1 double and clarity as
1x6878 double. Does any reason exist for such behaviour?
Best regards, Igor
