SeDuMi.jl

SeDuMi.jl is wrapper for the SeDuMi solver.

The wrapper has two components:

• an exported sedumi function that is a thin wrapper on top of the sedumi MATLAB function
• an interface to MathOptInterface

This wrapper is maintained by the JuMP community and is not an official wrapper of SeDuMi.

SeDuMi.jl is licensed under the MIT License.

The underlying solver, sqlp/sedumi is licensed under the GPL v2 license.

In addition, SeDuMi requires an installation of MATLAB, which is a closed-source commercial product for which you must obtain a license.

To use SeDuMi with JuMP, do:

using JuMP, SeDuMi
model = Model(SeDuMi.Optimizer)
set_attribute(model, "fid", 0)

First, make sure that you satisfy the requirements of the MATLAB.jl Julia package, and that the SeDuMi software is installed in your MATLAB™ installation.

Then, install SeDuMi.jl using Pkg.add:

import Pkg
Pkg.add("SeDuMi")

If you get the error:

Undefined function or variable 'sedumi'.

Error using save
Variable 'jx_sedumi_arg_out_1' not found.

ERROR: LoadError: MATLAB.MEngineError("failed to get variable jx_sedumi_arg_out_1 from MATLAB session")

The error means that we couldn't find the sedumi function with one output argument using the MATLAB C API.

This most likely means that you did not add SeDuMi to the MATLAB's path, that is, the toolbox/local/pathdef.m file.

If modifying toolbox/local/pathdef.m does not work, the following should work, where /path/to/sedumi/ is the directory where the sedumi folder is located:

julia> import MATLAB

julia> cd("/path/to/sedumi/") do
           MATLAB.mat"install_sedumi"
       end

julia> MATLAB.mat"savepath"
