Using function simple equation doesn't work

Hello guys,

Could you tell me why my function doesn't work, without block "fcn" - "Pikr1" everything works and scope shows me results.

How to use this "fcn" block, I would like to put there my own variable which is counted from output "p".

Greetings,

Krystian

Next time, I ask you to add more info so people can help you easily and not only with a photo.

The problem here is the block fcn "Pikr1" accepts as parameter a formula with the input u. So if you want to do p*p you have to input in the fcn block the formula u*u.

Thank you,

It works, but what in situations if I have many inputs and need to write an equation in one "fcn" block.

I know it is possible with "MUX" but what should I do next with this?

Greetings,

K.

I think I found out the answer I just write "u(1)*u(2)" for example

You are right, use "u(1)*u(2)"
