```julia
using EmpiricalModeDecomposition
a=convert(Vector{Float64},rand(20))
s=
EMD_heping_1MX_V_35kV1=EmpiricalModeDecomposition.hht(a,s)

```

This is my code,I don’t know how the keyword S should be defined, this is the code in the Pkg description:

```julia
hht(signal::Vector{Float64}, s::EEMDSetting)

```

And this is Pkg’s website:  
[https://juliahub.com/docs/EmpiricalModeDecomposition/c9SYr/0.1.1/autodocs/](https://juliahub.com/docs/EmpiricalModeDecomposition/c9SYr/0.1.1/autodocs/)  
It doesn’t say what should s be.How do I define s?thanks!

If a function is not described in the docs it’s often helpful to read the tests of a package. In this case it seems the tests don’t include `hht`, but other functions that take an `EEMDSetting` as their second input:
