To my knowledge this is only possible if all target machines have Matlab installed (or the MCR).
An alternative would be to use Coder to generate C code from your functions and compile that to a stand-alone application. There are many restrictions, so this might not be possible. It will probably require a substantial rewrite.
Another option I personally use is to modify your code to make it compatible with GNU Octave. The zip versions are portable. You should check if your use case is allowed by the terms of the license. Going this route will sacrifice a lot of performance and might require you to implement missing functions. Octave is not a drop-in replacement for Matlab, but in some cases they can serve a similar purpose.
