unwrap: "if enable phase inversions are eliminated"
As for the errors: you will need to show us the error messages you are encountering.

It's easy enough to do yourself. You can use bwboundaries() to get a list of boundary coordinates. Then loop over them and figure out which of the 8 directions the next pixel in the list is and assign a number from 1 to 8 to that pixel.
boundaries = bwboundaries()
x = boundaries(:, 2);
y = boundaries(:, 1);
for k = 1 : length(x)-1;
thisX = x(k);
thisY = y(k);
nextX = x(k+1);
nextY = y(k+1);
if nextX == thisX
% and so on.....
end
It's late here, so see if you can complete it yourself. It's easy.
