Combine this package with SparseMatricesCOO

[tmigot]

We could probably simplify a few things using https://github.com/JuliaSmoothOptimizers/SparseMatricesCOO.jl

• SparseMatrixCOO instead of COO

  NLPModelsJuMP.jl/src/utils.jl

  Line 28 in c05a30f

  mutable struct COO

• Move coo_sym_dot

  NLPModelsJuMP.jl/src/utils.jl

  Line 74 in c05a30f

  """

  to https://github.com/JuliaSmoothOptimizers/SparseMatricesCOO.jl/blob/main/src/coo_linalg.jl
• Move coo_sym_add_mul!

  NLPModelsJuMP.jl/src/utils.jl

  Line 74 in c05a30f

  """

  to https://github.com/JuliaSmoothOptimizers/SparseMatricesCOO.jl/blob/main/src/coo_linalg.jl

It's an excellent idea @tmigot, I didn't find the time to look at SparseMatricesCOO.jl but we should use it as a dependency of NLPModelsJuMP.jl.

[dpo]

I think it should be a dependency of NLPModels to begin with.

Agreed, this is connected to JuliaSmoothOptimizers/NLPModels.jl#389
