Hi!
If you have trouble defining functions in Matlab, start here: http://www.mathworks.com/help/matlab/matlab_prog/create-functions-in-files.html

Please use coder.varsize to define an upper-bound for the output variable as I have previously explained here. You also need to configure the MATLAB Function block for a variable-size output.

For this particular piece of code, variable-sizing should not be needed as the end points are constants. This example works fine for me in a recent version. What version of MATLAB and Simulink are you using?
You can find this out using the ver command: >> ver
