C compiler error in using quadprog in a simulink model using coder.extrinsic.

I am trying to build a Simulink function block using the "Matlab Function" block for simulink. I just want to see the output on a scope so I connected the Matlab Function block to a scope. When I run the code, it gives me an error saying there is no C compiler. I am not sure why I would require a C Compiler for just running a normal simulation. Can anyone help me with this?

I have the Matlab R2013a version.

Thanks for your time,

Regards

The MATLAB Function Block requires a supported C compiler even for simulation:

That link shows how to install one if it is not present. If you already have a compiler installed then:

mex -setup

will guide you through choosing it.

Thank you for the answer. I was not sure about that. So, is there any other block that would be similar to the Matlab Function Block but does not require a C Compiler?

Thanks

The interpreted MATLAB Function Block and Level-2 MATLAB S-Function block should not require a compiler:

Most platforms either come bundled with a compiler or have freely available supported compilers as well. For R2013a:
