My MATLAB Version is 7.11.0.584 (R2010b) and i am trying to run a simulink model on it.
But an error occur during the parsing phase: "Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds. Use 'mex -setup' to select a supported compiler."
So i t typed mex -setup in the MATLAB command prompt and it appears that there are no compiler available. So how do i get the compiler to allow my simulink model to run successfully?
Thanks

nikhilsinghgangwar, which MATLAB version are you using, and exactly which compiler have you installed? Did you install VS Professional, VS Ultimate, VS Community, VS Express ?

I guess you run Matlab on 64-bit platform (The factory LCC is the only available for 32). A free compiler is Microsoft Visual Studio Express. You need to download and install it.

I also would guess this is that you need to install a C compiler. Here is the full list:
I heard people struggling with not correctly applying the right SDK for the MSVC Express editions, so my advice is to look at this very carefully.
