Using the colon vector in a simulink function

I am trying to calculate the interimvalues of a vector in SIMULINK. In MATLAB the code would look like this:

(u(2:end) + u(1:end-1))./2

The SIMULINK Function Block is unable to perform this operation because of the colon Operator ":" and the documentation only refers to the Math Function Block but it is not possible to enter a custom function there...

Do you know a simple way to calculate the interimvalues as described above?

Thank you very much for your help!

Looking at the help file for the Fcn block it does state:

Also, this block does not support the colon operator (:).

so I guess that isn't going to work. You can build the expression in Simulink using Selector blocks, but probably the simplest solution is to use an Embedded MATLAB block with:

function y = fcn(u)
%#eml

y = (u(2:end) + u(1:end-1))./2;
