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?

Hi Jan, do you know how to use a variable input for a MEX file function. I have posted my question here: https://uk.mathworks.com/matlabcentral/answers/408136-ho-to-use-a-dynamic-array-in-a-mex-file-function
I hope you could help me.

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
