Recovering different form from JuMP model

[odow]

There’s no simple way.

This question has some code to help. The solve_pdhg function provides A, b, c (for Ax = b):

Connecting a simple first-order solver to solve standard form linear program to JuMP

Try this: module SimplePDHG import MathOptInterface as MOI import SparseArrays """ solve_pdhg( A::SparseArrays.SparseMatrixCSC{Float64,Int}, b::Vector{Float64}, c::Vector{Float64}, )::Tuple{MOI.TerminationStatusCode,Vector{Float64}} """ function solve_pdhg( A::SparseArrays.SparseMatrixCSC{Float64,Int}, b::Vector{Float64}, c::Vector{Float64}, )::Tuple{MOI.TerminationStatusCode,Vector{Float64}} x = fill(NaN, size(A, 2)) return MOI.OTHER_ERROR,…

You shouldn’t rely on th JuMP._standard_form_matrix function. Function beginning with _ are private and may change or be delete at any point.

This questio keeps coming up, so I should add an answer to the documentation: Suggestions for documentation improvements · Issue #2348 · jump-dev/JuMP.jl · GitHub
