Getting MATLAB.jl on Windows to work

General Usage

1

Hello everyone, I raised an issue on the GitHub repo but looks like it’s not very active so just wanted to see if anyone else had this problem and a fix.

I’ve added MATLAB in Julia v1.11 through the package manager. I am running Windows 11 and MATLAB 2024b is installed. When I run

using MATLAB  # this is fine
mat"ver"

or any other MATLAB code in VSCode, I get:

The terminal process "C:\Users\testacct\.julia\juliaup\julia-1.11.2+0.x64.w64.mingw32\bin\julia.exe '-i', '--banner=no', '--project=C:\Users\testacct\.julia\environments\v1.11', 'c:\Users\testacct\.vscode\extensions\julialang.language-julia-1.127.2\scripts\terminalserver\terminalserver.jl', '\\.\pipe\vsc-jl-repl-159c2360-275d-4eda-9708-5697120d6478', '\\.\pipe\vsc-jl-repldbg-34439aaa-b352-4163-8607-b71adecda219', '\\.\pipe\vsc-jl-cr-929cae24-af6b-48c7-a83a-58fad01bbf68', 'USE_REVISE=true', 'USE_PLOTPANE=true', 'USE_PROGRESS=true', 'ENABLE_SHELL_INTEGRATION=true', 'DEBUG_MODE=false'" terminated with exit code: -529697949.

When running just the Julia terminal without VSCode, the terminal just closes. However, I have noticed that the MATLAB Command Window will pop up before exiting.

When I test the build:

ERROR: Package MATLAB errored during testing (exit code: 3765269347)

After testing I have checked “C:\Users\TESTACCT\AppData\Local\Temp\jl_tkJSKc” and it appears to be empty.

I believe this gentleman had the same error and suggested running the Julia terminal in Administrator mode for installation and testing.

Having tried this I got no change in the outcome. Still same error in my case.

Many thanks if you can suggest something else to try.

I skim through your issues related to MATLAB.jl, I am wondering if there is a general pause solution to Julia packaging on Windwos? I ran into similar problem just updating packages, it tried to rm anon-empty temp directory, by the time I navigate to the location it appears to be empty.

3

As far as I understood, MATLAB.jl only reliably supports versions up to Matlab R2022a.

4

I’ve been using MATLAB.jl without issues on Windows 11 with R2024b using both Julia v1.10 and v1.11.

Sounds like MATLAB.jl might not be handling the COM interface well on Windows 11. I had a similar issue. Running Julia and VSCode as admin helped a bit, but switching to Julia’s REPL outside VSCode finally did the trick. Also, double-check MATLAB’s path in ENV["MATLAB_HOME"].
