Automatic Differentiation for gamma and psi functions

Is there a way to make automatic differentiation work with MATLAB functions gamma and psi? I can use equivalent custom functions but it is not quite as elegant.
I am using automatic differentiation equivalent to rosenbrock example in https://www.mathworks.com/help/deeplearning/ug/include-automatic-differentiation.html. When I try to use gamma function of psi function in the differentiated function the code ends with error that dlarray is not supported input for the gamma and/or psi function.
If the psi and gamma are just not supported can you recomend a place where I can angrily write that MATLAB is basicaly unsable and ask for this feature to be in the new update? :D

Currently, dlarray support is not available for gamma and psi. I have brought your request to the notice of concerned people. As a workaround, you can write a function that implements the aforementioned functions using other functions that have dlarray support.
In general, to request any new features, see How can I make a features request?

I don't understand why automatic differentiation is needed although there are custom MATLAB functions for the derivatives of gamma and polygamma.
