I'm having an error on the 'bwareafilt' part. it says "Undefined function 'bwareafilt' for input arguments of type 'double'."

It is available from 2014B...it seems you are using a lower version.

[Ramon Ticzon]

That's why. I am using 2014a. Is there a way to do it in 2014a?

[Ramon Ticzon]

Thank you, Sir. It works on other version. I used 2017a
