Where I can find helperCalc​ulateCoupl​ingMatrix.​m function ?

Hello, everyone ! I need to simulate crosstalk(coupling)effect in MIMO system. So I found a good example on mathWorks: https://www.mathworks.com/examples/aa/mw/antenna-ex21652905-effect-of-mutual-coupling-on-mimo-communication

But there is no the main function helperCalculateCouplingMatrix.m in the Antenna Toolbox. Also a don't know where I should find it. So please help me. Where I can find this function ?

It's a helper function for the example. If you open this example in MATLAB, there should be a button you can click to open the example script. Once you click the button, you will be able to see the function.
