Once I obtain the scalogram coefficients and can make an image of them with this code.
[S,U] = scatteringTransform(sf,wecg);
How can I retrieve the matrix that makes this image? U is a 3x1 cell where wach cell contains a different number of cells.
I don't understand how to plot U (without scattergram as above) in a way that still make sense. I just want the matrix of the image formed with this code.
