Mex or Compile (mcc) Matlab function that uses toolkits

Environment:

I am working with the source for a software package written in Matlab (unfortunately its proprietary so no code examples...sorry), and one function briefly uses the Control System Toolbox and the Signal Processing Toolbox.

I have no problem running the code on my personal computer because I have every toolbox installed, however I would like to compile (mex or mcc) JUST the function using those two toolboxes. The goal, of course, is to run the software on a machine without those toolboxes, while leaving the remaining code open to change.

According to matlab, they have no problem with you compiling code that uses almost any toolbox. Here is the list of toolboxes that support mcc compilation: http://www.mathworks.com/products/compiler/supported/compiler_support.html

The problem arises in that mcc no longer allows compiling with the -x option to create a mex-ed version of the function, so I'm forced to create a C executable (maybe? hopefully not). This particular function takes large matrices as parameters (impractical to write as a command line argument) and returns a structure of cell arrays.

The only way around this (as I see it now) would be to write the arguments (large matrices) to the hard drive in a binary .mat file , have the compiled C binary read in the arguments, run the algorithm, and finally save the return values in another .mat for the parent thread to load back into memory.

This seems totally impractical. I would greatly appreciate alternative suggestions. Please let me know if anything here in unclear. Thanks in advance!

[Edit 1] The codegen package does not support tf.m. It seems like this should be possible (and used to be possible with the mex -x option), but I'm at a loss. Any suggestions would be greatly appreciated!

I think the reason -x is not supported anymore is the fact that Matlab now has a product called "coder", which converts .m files to .c files and can also create .mex files from "suitable" .m files using the option -args to specify the input arguments: http://www.mathworks.com/videos/generating-c-code-from-matlab-code-68964.html
