Why MATLAB fn block and S function block are not supported for RTW code generation?

Why MATLAB fn block and S-function block are not supported for RTW code generation?

The Interpreted MATLAB Function block is not supported for code-generation, but the (Embedded) MATLAB Function block does generate code as long as you are only writing MATLAB language features supported for code generation. You can also generate code from MATLAB S-functions by providing a TLC file that includes the C implementation for the block (see Inlining S-Functions for more information).
