smat = featureMatrix(sf,x)
[smat,u] = featureMatrix(sf,x)
smat = featureMatrix(___,Name,Value)
I thought smat were the scattering coefficients and u were the scalogram coeffcients, however, when I plot smat, I do not quite uderstand what I am looking at, it does not look like the low frequencies of my signal. So, my question, is smat not the opposite of u? what is smat returning, matematically speaking?

Greetings,
featureMatrix function returns returns the scattering coefficient matrix. Please refer to the following documentation link.
