I don’t think there’s an easy way to do this in JuMP.

There are two complicated ways:

- Write functions to parse the JuMP model and extract the coefficient matrices. Look here for inspiration: [https://github.com/jump-dev/JuMP.jl/blob/2875bd1a0d336215a63ffb0fe74ffaaad0a6979a/src/lp\_sensitivity2.jl#L302-L350](https://github.com/jump-dev/JuMP.jl/blob/2875bd1a0d336215a63ffb0fe74ffaaad0a6979a/src/lp_sensitivity2.jl#L302-L350)
- Create a MOI model that supports quadratic objective and quadratic-in-less than, then write a function to extract the matrices from the MOI model. Look here for something similar with LPs: [cplex - Standard Form for LP and MPS - Operations Research Stack Exchange](https://or.stackexchange.com/questions/6982/standard-form-for-lp-and-mps/7003#7003)
