Overview
Comment:`mtt sys sfun zip` now produces an input block and an interface block for MTT models.
Models can be embedded within larger Simulink models by the 2 ports.
The user must edit 2 code blocks in <sys>_sfun_interface.c before compiling with mex.

To build a Simulink funtion of the <mtt_model_name> model without using MTT:

mex <mtt_model_name>_sfun.c

The input block can be created with:

mex <mtt_model_name>_sfun_input.c

If numerical solution of algebraic equations is also required:

mex <mtt_model_name>_sfun_ae.c
