How to calculate the dot product of vectors and display Hidden Variables

Hello,

I'm looking for a solution to a problem I'm having with AWE.

I am looking into whether AWE can provide the same functionality as a model designed in Simulink.

The first is the calculation of the dot product; in Simulink there is a "dot product" block, but not in AWE Designer. I tried to implement the equivalent functionality in an existing module, but it did not work.
Please let me know how to solve this problem.
Attached are the relevant Matlab/simulink pages and an image of the formula to be realized.

The second question is about the display of hidden variables.

AWE Designer has modules that have hidden variables, and I want to view and edit these hidden variables.
I understand that I can use the MATLAB API to view and edit them via MATLAB. However, I would like to do this on AWE Designer.
