The level2 matlab sfunction block allows you to write your sfunction using the matlab language. The matlab function block is compiled before runtime r2014b and earlier, it generates c code and compiles. To determine the output dimensions, simulink runs the function or expression once before simulation starts. The simulink accelerator software runs level2 matlab sfunctions in interpreted mode. The interpreted matlab function block uses the matlab interpreter to execute an existing matlab function. However, to reduce memory requirements for working with images, you can store images as 8bit or 16bit unsigned integers using the numeric classes uint8 or uint16, respectively.
