syntax error in simulink

i cannot run my simulation due on this function. can you help me to identify the problem.

p(1)*u(2) + p(2)*u(1) + p(3)*u(1)*u(1) + p(4)*u(1)*u(2) + p(5)

Exactly what kind of block were you using, and how many input ports did it have?

[Fadzliana Aida]

I am new in simulink, and also have no basic in simulink. and i cant figure out the problem. please help me on my project. the error function was in the intake manifold. thank you for your response.

[Walter Roberson]

In what you attached, there is no intake manifold, and no blocks that might have the error you posted.

Answer 1

[Fadzliana Aida]

is the internal parameter of the throttle and manifold, there's a intake manifold. when you click twice there are a block convert to mass change and that is where the synax error function happen.

[Walter Roberson]

There are nothing marked as being throttles or manifolds in what you posted.

Answer 2

[Fadzliana Aida]

here sir. hope you can help

[Walter Roberson]

That code works fine when I try it in isolation.

I have attached an example model that uses the block typed in by hand (since you have not attached the actual block.)

Note that in order to use it, you must have a workspace variable named p that has at least 5 elements. The fcn block can use variables other than u but they must be workspace variables.

my simulation is work. thank you so much for your help
