Hiding simulink model content with s-function

hallo,

i want to hide some subsystem in my simulink model from third-party viewers. i found an answer here: http://www.mathworks.com/matlabcentral/answers/25625-hiding-model-content

but when i convert my subsystem to s-function, these s-function can not be compiled (to .dll) without .c and .h

is it possible, that i only give third party viewers .mex file, and they can compile the s function to dll?

or can i convert the c source code to some unreadable code?

The .mex (or .mexw32) is a compiled file. You don't need to compile it into dll file. If you give to your third part your model and your mex file, it is ok.

thx for ur reply!

but i really need to compile the s function...

problem is: i have a simulink model, i don't want to share content of some subsystem in it, so i convert them to s function. but the other subsystems are open to the third party viewers, they can rewrite them.

after rewriting, the simulink model must be able to compiled in a .dll file, in order to use it in another software. but this compiling requires c source code.
