Error using loadlibrary when trying to load dll

I'm trying to use Dr. Kadir's NP windows code. He says it's MATLAB code written in C/C++ and there are .m and .dll files. More specifically, I'm trying to use PDF1DLinear. But when I do loadlibrary('PDF1DLinear'), I get an error: Undefined function or variable 'PDF1DLinear_proto'. Am I not loading the library properly? Am I missing a file?

To load a library, you will need a header file specifying the signatures of the functions used in the DLL.

Those are old mex files probably for a version of MATLAB before R2007a. If you have an old 32 bit version of MATLAB you may be able to get them to work otherwise contact the author for the source and rebuild them for a current version of MATLAB.
