Bus signals from simulink functional block

Hey everyone,

I am trying to get bus data in and out of matlab function block in simulink. Here's a simple model I have tried to test to it out:

The function is defined as :

function y = fcn(b1, b2)

y.b1 = b1 - b2;
y.b2 = b1 + b2;

I have created a simulinkBus; "x" as shown in the image below:

But I keep getiing this error, when I run my model:

What am I doing wrong here?

Hey Alex,

Thanks for your suggestion. I have been following the information from the link you recommended, but to no avail.

And, I also can't find "Ports and Data Manager" in my simulink toolstrip.

Regards,

Neal
