Scattering feature matrix

returns the scattering feature matrix with additional options specified by one or more
`smat`

= featureMatrix(___,`Name,Value`

)`Name,Value`

pair arguments.

The

`scatteringTransform`

function calls`featureMatrix`

to generate the scattering and scalogram coefficients. If you only require the coefficients themselves, for improved performance the recommended approach is to use`featureMatrix`

. Use`scatteringTransform`

if you are also interested in the coefficients metadata.
