As the title says, how to I visualize with a scalogram the different outputs of the scattering transform? In the same way that is done in this figure from this paper https://arxiv.org/pdf/1304.6763.pdf where at the top there is the signal, middle it's first layer of the scattering transform and third the second layer.

Hi Lucrezia,
Once you have already computed the scattering transform coefficients and stored them in a variable, you can use the 'imagesc' function in MATLAB to visualize the different outputs of the scattering transform, including higher order levels. The 'imagesc' function is used to create a visual representation of the coefficients, with the magnitude of each coefficient represented by a color. Then you can use the 'colorbar' function to add color scale to the plot.
You can refer to the documentations below to know more about these functions:
Hope this helps
