How do I reduce the size of the functions generated using the Stateflow Coder 4.2 (R12.1+)?

I have generated code from a Stateflow chart and there are a few small functions and a very large void function. This is a big problem because many embedded compilers, such as Hitachi, refuse to compile functions that are too large. I would like to know how to reduce the size of this function.

If you are using Stateflow 4.2 (R12.1+), you can set both minimum and maximum thresholds as follows:

sfc('coder_options','inlineThreshold',10)         % only functions with < 10 statements get inlined

sfc('coder_options','inlineThresholdMax',100)    % if caller has > 100 statements, no more inlining done

The values used for the parameters above are just examples and actual numbers would be user specific.
