I have posted the error below, I am new to Julia and would take any suggestions on interpreting/fixing it:

MethodError: no method matching kron(::Array{JuMP.GenericAffExpr{Float64,JuMP.Variable},2}, ::UniformScaling{Int64})

Closest candidates are:

kron(::Any, ::Any, ::Any, ::Any…) at operators.jl:424

kron(::Union{Array{T,1}, Array{T,2}} where T, ::SparseMatrixCSC) at sparse\linalg.jl:785

kron(::AbstractArray{T,2}, ::AbstractArray{S,2}) where {T, S} at linalg\dense.jl:313

It would be helpful if you could also post your input.

I find `UniformScaling`

slightly awkward to use in that it is not an `AbstractArray`

(i.e. it doesn’t not always behave like an array), so it doesn’t always have methods defined for it).

Try

```
kron(x, Diagonal(ones(N)))
```

where `x`

is your first argument and `N`

is the number of dimensions in your second argument. This should work but is probably not the most efficient way of doing whatever it is you’re trying to achieve.

Thank you! I may give more information when I can for better performance however your suggestion has worked in the meantime.
