How to declare local functions in an embedded matlab function block.

I declared local functions in an embedded Matlab function block and I want to know if I have well coded it. The problem is that, my local functions uses some of the inputs of the main function. I would like to know how can we call local functions that uses the inputs of the main embedded matlab function block.

Thanks

Please also paste sample code to make the question clearer. In general, you would simply have to pass in the data as input arguments to the local function.
