MEX Creation of a Function with Input Parameters

I am trying to generate a MEX file of a function that has input parameters (like 'function [] = run(inputfile)', but emlmex gives me a an error about preconditions. I have several functions that are calling each other and passing information between them, and I want to make MEX files of all of them in an effort to speed up processing.

Any ideas how I get around this "precondition" problem?

Thanks.

I see that I can use '-eg' when calling emlmex, but that seems to require me to specify exactly what I am loading, but in instances where I am trying to load a matrix or vector of unknown size, this does not work.
