Is this correct?

Bonjour,

if I want to compute the ESRI of a whole economy. Is this how to do it?

```julia
M = prepare_reference_market(W, industry_ids, essential)
A = ReferenceRepo.buildArrays(M)
psi_all = spdiagm(0 => ones(n))
params = Dict("tmax" => 100, "timeseries" => false)
df = ReferenceRepo.ESRI(M, A, psi_all, params)
```

Or does the code work better if the psi_all is separated? Say one-by-one?

Thanks!
