You do not "open" such a file, because it is a compiled function. You call it exactly as any other Matlab function.
Why do you want to "open" the file?

This means, that you are working with codegen and do not write the C-Mex function manually.

Hi,
maybe I can help you, because I came across this post when looking for "how to open a mex file". Now I understood that is a compiled function (thanks Jan), but I still wanted to double check the underslying .m file where this function was created from.
My mex file was created by using the Matlab coder. I created it from a .m file. Matlab generated automatically a folder named "codegen", and inside this there is a folder named "mex". In this folder, I can find the folder that has the same name as my original Matlab file. Inside this folder, I see the "html" folder and there, finally, I find the report.mldatx. In this report, I can double-check the original .m function associated to the compiled mex file.
Hope this helps!

Hi Maria, in the following link you can see how I organised my files in order to use a mex file function. I hope this contributes as well. https://uk.mathworks.com/matlabcentral/answers/408136-ho-to-use-a-dynamic-array-in-a-mex-file-function?s_tid=prof_contriblnk
