Hi,

Firstly, you can specify the number of Inputs, Outputs, states and parameters an S-function has using 'mdlInitializeSizes'. Refer the following documentation link for details:

• http://www.mathworks.com/help/simulink/sfg/mdlinitializesizes.html

Then get hold of a parameter using 'ssGetSFcnParam'. More details can be found at:

• http://www.mathworks.com/help/simulink/sfg/ssgetsfcnparam.html

Check the example mentioned in the above link for reference and use the Matrices to calculate product in the S-function.
