I want to create a 64-bit .dll file using c code and get it
working with a matlab script on a 64 bit machine. Has
anyone tried doing this, or knows how to do this? It works
on a 32 bit machine, when it's obviously a 32-bit .dll file.

When I try, I get the following error: "Undefined function
or method for input arguments of type 'char'".

Do you mean recompile on a 64bit machine using a 64bit compiler? Have
you done this?

You can also cross-compile to a 64bit target from a 32bit machine if you
have the cross-compiling tools set up, but I'll leave that as an
exercise for the user (note that I have this set up).
