Issue with kruskalwallis() function not working in Live Script after installing MATLAB R2025a

Hi everyone,

After installing MATLAB version R2025a, I noticed that some functions freeze and do not run at all in Live Script. For example, the function kruskalwallis() completely freezes when executed within a Live Script, but it works normally in the Command Window and regular scripts.

Has anyone else experienced this issue? Is there any known solution or workaround?

Thank you in advance for your help!

I can replicate the hang on my R2025a Mac Intel system.

Interestingly, it works fine here in MATLAB Answers, which uses LiveScript technologies underneath.

pd1 = makedist('Normal');
pd2 = makedist('Normal','mu',2,'sigma',1);
rng('default'); % for reproducibility
x = [random(pd1,20,2),random(pd2,20,1)];
p = kruskalwallis(x)

p = 3.6896e-06

On R2024 it runs well. It seems that this problem is specific to R2025a. Maybe I need to revert back to R2024b until this issue is resolved.

It happens that there is a seperate report tonight of graphics hanging in mlx files, this time when subplot() is used. https://www.mathworks.com/matlabcentral/discussions/tips/881887-there-is-an-error-in-the-subplot-function-in-2025a-version/2620277#reply_2620277

Hi Geovane Gomes,

I too encountered the similar issue. The workaround that worked for me was to disable the plot output. Kindly use the following command to disable the plot while calling the "kruskalwallis" function. However using this command will execute the "kruskallwallis" with ANOVA table and stats in MATLAB R2025a in live Script but it will not generate or display associated plot.

[p,tbl,stats] = kruskalwallis(x,[],'off')
