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
