creating a dll from .m function and using it in matlab as shared librery

Hello , I am creating a matlab gui which activates a certain simulation. I am creating the gui , and another guy is creating the simulation itself as a single .m function. I have compiled the gui+simulation into an .exe and it all wokrs just fine. (the reason for the .exe is that the people who uses it , does not have matlab and I also dont want to give them our simulation source code). I would like to use my gui with several other simulations which fits the gui , which means that i would like to compile the simulation (.m function) as a dll and use that dll in my matlab gui which would be compiled to .exe. (the actual dll file that would be in the same directory as the exe file is the actual simulation that would be invoked.

I have tryed using the mcc but it just created a dll to use in c. So how can i do it?

Thanks Eran.

As I understnad it you cant compile a dll from matlab m code which matlab will be able to load.

i.e. m code -> dll -> load_into_matlab is not possible

So are you familiar with another way of doing it?

I need to call to a matlab function from another matlab gui which was built into .exe file , and without exposing the sourcecode.

Thanks ,

if everything is compiled at the same time you can use native m or p-code. But if your exe is compiled before and you want to change the dll without re-issuing the exe you cant.

If mcc created a dll for use in C, you could possibly call it from MATLAB using calllib()

[Robert Cumming]

as far as I know calllib cannot load dll which originates from matlab code - its a restriction put inplace my TMW.

I succeded in loading the dll but i couldnt make the function to work
