You do not state what format or language you are trying to convert to?
I have attached a link to MATLAB Complier SDK as a starting point. I should point out that conversion will not necessarily give you an efficient or elegant result. Manual conversion is often best.
It can get a little more complicated with FPGAs, but Xilinix and Altera have toolkits that should be able to assist.
If you can provide further information I am sure you will receive some refined answers.
It is important that you mention the language to which you want to convert MATLAB programs or from which you want to convert. However, if you have written the program in MATLAB and want it to be converted to VHDL etc. it is possible. It is also possible to deploy MATLAB programs as a standalone package. Besides if you have written a program in C and want to execute it in MATLAB, it is possible to do so. I would suggest you to explore the MATLAB help directories to know more in this regard.
The quickest way is to search on the internet for the language translators to see if it is available a free released translator that translates from the language you have to the other one. I have a real experiment since I found a Translator translates a very long code From FORTRAN to Ansi C-standard. The code works very well, of course no customization for the code but any way it works properly.
