I need to compile .mex files from path folder. Is there any command for that or any other process for compiling mex files. Below are the files
Suppose I need to use this function mex_pb_parts_final_selected in demo.m file and it gives me an error mex_pb_parts_final_selected function is not exist. Can someone guide me how I resolve this error? Thanks

These files are compiled already for MacOS computers. If they cannot be accessed from am M-file, either the folder i not included in the path, or you do not run Matlab on a Mac.

Hey Jan, I am using windows OS and main.m file I already includes these paths as below
addpath(genpath(('third_party/Tardif')));
addpath('third_party/BSR/grouping/lib');
addpath('mexFunctions');

@Gundeep: Prefer using absolute paths. If e.g. the folder "mexFunctions" is in the current folder, use:
addpath(fullfile(cd, 'mexFunctions'))
Maybe addpath() tries to o this automatically, but the explicit definition of the wanted folder is safer.
As I've written already, the mex files are compiled for MacOS and cannot be used under Windows. You need the source codes in C or C++ and compile them for Windows. If you do not find the sources or instructions for a compilation, you have to contact the authors.

I am not the administrator for that website nor for your computer, so I can't fix that for you. When I right-clicked that link and chose the 'save link as' option I was able to save the tgz file. If you are unable to do so, you will need to contact the administrator for that website, or your computer, or both.

@Gundeep: When I click on this link, the download starts directly. Unpacking fails due to missing rights to create symbolic links, but I assume unpacking with admin privileges will work. The file is too big to be posted here as attachment.
How to download a file from the web is not a Matlab problem.

I don't understand. Like Jan said it looks like they have already been compiled into mex files. Do you want to compile your demo.m file that uses those .mex files? If so you might need to use the -a option in mcc or else just put the full path to them when you call loadlibrary in your .m file code.
If it says that it can't find mex_pb_parts_final_selected(), then that function is not in your demo.m file like you thought and it's not anywhere on the search path. Try putting it in the same folder as demo.m.

Hello, in the below path this function exist mex_pb_parts_final_selected() is located and demo.m file is located on another path. Can you guide me for this?

Which DLL is mex_pb_parts_final_selected() trying to call?
Which DLL is for the Windows platform? You can't call a mex file made for a Mac.
Use the SetPath button on the Home tab of the tool ribbon and make sure you save the path, or make sure you call setpath() after you call setpath().
