It would be a lot easier on us if you showed us a copy of the error message. And also if you told us which MATLAB version you are using.

Heyya ,

I have executed your code snippet and I don't see any error in the code.(except one single error)

In my case , I got an error because , The image which i imported pout.tiff was of type LOGICAL . I just converted those variables A and Ref to double type using A=double(A) ..

Apart from this the code is working fine.(until unless your A and ref are logical type , you should not get an error)
