Aren't both funxtions supposed to give you the continuos wavelet transform coefficients?

What's the difference between these two functions?

cwt function – It performs the continuous wavelet transform (CWT) for the given input signal. It returns the wavelet coefficients which are function of scale and position.

scatteringTransform function - It performs the wavelet scattering transform for the given input signal and the scattering decomposition framework which is specified as a waveletScattering object. It returns the scattering and scalogram coefficients.
