why are the scalogram coefficients given in a table rather than matrix?

Hello,

I am trying to get the scalogram coefficients from U, filterbank 2.

s = scatteringTransform(sf,x)

[s,u] = scatteringTransform(sf,x)

scattergram(sf,U,'FilterBank',2)

The resulting scalogram coefficients are given in a table. I don't know how to use this. I just want the coefficients like when cwt is applied.

How can I get these?

I would like to use a filterbank that allows only slow changing features to get through, hence the need for the filterbank 2.

Thanks!
