What is numbers being set to on each iteration of the loop? Please show your updated code.

Assign numbers like this:
numbers(plotIndex) = length(B);
You need to define newID.
Also, call xlswrite() just once after your double for loop.
And your look over k just puts up a label for each boundary in the same place at (10,10), which seems unwise.
