How to compute haar integral over a unitary group?

I want to calculate haar integral over a unitary group. Mathematica has a package to do this. I wonder if matlab has the same packages?

No.

But it's not a special Mathematica package. It has been developed by the authors of the article using Mathematica. And this is something you could also try using MATLAB's symbolic toolbox.

I haven't used MATLAB's symbolic toolbox before. Maybe I should try it. Before that, I want to make sure one thing. Did you mean I can directly use the code developed for Mathematica instead of writting one of my own? Thanks!

Yes, if the authors are willing to share the code, if the code works and if you use Mathematica.
