Scattering feature matrix

returns the scattering features for the scattering decomposition framework
`smat`

= featureMatrix(`sf`

,`x`

)`sf`

and the input signal `x`

.
`x`

is a real-valued vector or matrix. If `x`

is a
vector, `smat`

is an *M*-by-*N* matrix,
where *M* is the number of resolutions across all orders of the scattering
transform, and *N* is the resolution of the scattering coefficients. If
`x`

is a matrix, `smat`

is an
*M*-by-*N*-by-*P* array, where
*P* is the number of columns in `x`

.

The precision of `smat`

depends on the precision specified in the
framework `sf`

.

returns the scattering feature matrix for the cell array of scattering coefficients
`smat`

= featureMatrix(`sf`

,`s`

)`s`

. `s`

is the output of `scatteringTransform`

applied to an input signal for the scattering
decomposition framework `sf`

.

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