Hello, I approached to wavelet transform because I need a better time frequency representation than I get actually from multiple short FFT.

I've read the very well done tutorial at "http://users.rowan.edu/~polikar/wavelets/wttutorial.html"
I need exactly what is shown in that tutorial : an amplitude of frequencies over time representation.

As shown in this gif of that tutorial : http://users.rowan.edu/~polikar/WAVELETS/figure1_11.gif
I need to create a tri-dimensional array, where one dimension is time that is related to input samples ( in that gif is the "translation" axis), the other is the frequency ( in that gif is the "scale" axis ) and obviously the "amplitude" axis.

Seeing Wavelets Studio and docs about the DWT block, I can't figure how I can extract tri-dimensional data from DWT block.

It's possible to know, giving a number of input samples how I can get these data ?
I need to obtain an array wide : 100(Scale) x InputSamples that contains the Amplitude value at each location.
With that data I can draw a tri-dimensional image like that shown in tutorial, that is reason of existence of Wavelets.
Many thanks for reply.
