I've edited the message to apply a code formatting. Please use the "{} Code" button to post readable code.
I still cannot imagine why posters do not care about unreadable code. They want others to read and fix the problems and several times each day reminders are required. It would be very useful if MathWorks add a HUGE red reminder and explanantion of the "{} Code" button in the field for creating a question, at least for the first 5 posts of a user.

I do not find the argument "montage" in the help text om imshow .

The problem is in last line.
use :
figure,imshowpair(Ihmf,I,'montage');
imshow() doesn't have any property named 'montage'.
