I understand that DiffEqOperators.jl will be deprecated but it is still useful for me to solve some PDEs. Can anyone suggest to me how to resolve this problem?
using DiffEqOperators
dx = 0.1
Δ1 = UpwindDifference(1,2, dx, 10, -1)
bc = RobinBC((1., 0.01, 1.), (0., 1., 0.), dx, 2)
Δ1*bc*rand(10)
prompts the error:
ERROR: MethodError: *(::GhostDerivativeOperator{Float64, DerivativeOperator{Float64, 1, true, Float64, StaticArraysCore.SVector{3, Float64}, StaticArraysCore.SVector{1, StaticArraysCore.SVector{3, Float64}}, StaticArraysCore.SVector{1, StaticArraysCore.SVector{3, Float64}}, Vector{Float64}, Int64}, RobinBC{Float64, Vector{Float64}}}, ::Vector{Float64}) is ambiguous.
