Mtalab Simulink syntax error

Hi,

I am using the fcn block to create a disturbance obersever, however when running the simulation I recieve syntax error in the fcn block.

The expression is: u(1)/B1(1).

How can I resolve this?

What is the full and exact text of the syntax error you received?

[Clifford Osei]

The expression: u(1)/B1(1) in 'newobserver/Fcn' has a syntax error

[Giuseppe Inghilterra]

Have you defined somewhere parameter B1? Otherwise you get syntax error.

When i first built the model it was defined in a matlab function block and it worked fine. I now had to add it to the main script, thank you
