Hi Bob, Thank you for the very quick reply. Your answer helped me a lot. By the way I just realized bookplot is already plotting the Heisenberg boxes. Thanks again Nicolas

Hello Nicolas. Have a look at the code linked here: http://media.aau.dk/null_space_pursuits/2013/03/from-mptk-books-to-wivigrams.html

[forum:149105]

Hi,

I have decomposed a sound signal with the mpdecom function in Matlab. Now I'd like to plot the Heisenberg boxes for each atom in the time-frequency domain. Thus I need for each atom:
-its time location (I guess it's the atom(x).params.pos variable)
-its time resolution (I guess it's the atom(x).params.len variable and its unit is in samples?)
-its frequency resolution (this I have no idea where I can find it)

So please could you tell me where I can get the frequency resolution from?

p.s: I've seen these two threads mentionning support>I but I didn't get what it refers to
