I am working on vectorising my model and I got stuck when I tried to vectorise the if-statement block. I wonder if it is possible to do it in Simulink. I know that it will work if I get each singal individually and apply them to multiple of if-statement blocks, but this is not what I want to do. Any suggestions will be greatly appreciated!
This is what I want to do and the error that I get:

You can only apply scalars to the if port of action subsystems. Consider your example where you test:
out1_of_if_block = u1 == [1 2] = [1 0]
What do you expect the If Action Subsystem2 to do when [1 0] is applied to the action port?
Perhaps inside of the 'If' block, you would want to do something more like this:
u1(1) == 1
