time2=clock;%starts timer on clock 2.Searching for height difference in a 3 X 3 cell windowThe search begins in the cell with highest elevation. From there it examines all eightsurounding cells to find the next cell to go to. The first cell to examine is the upper left((x-1),(y-1)), seen from the highest elevation cell (x). Then it continous to search counterclockwise untill all eight are examined. The neighbouring cell with greater slope than anyother of the neighbouring cells, is the next cell, from where to continue the search. Thenext cell must not be the previous cell, have the value of zero and have a value greaterthan current cell. After the first ten iterations have been performed, it starts again at thecell with the second highest elevation. This is done repeatedly until all rivercells havebeen a starting point.for l=cells:-1:1;%loop from 1 to number of "cells".x=order(l,1);y=order(l,2);%variables "x" & "y" are given the coordinates from row "l" in "order".cell_height=0;%the variable "cell_height" is set to zero.height=0;%the variable "height" is set to zero.for m=1:10;%loop from 1 to 10.temp1=0;%the variable "temp1" is set to zero.highest_value=data(x,y);%the variable "highest_value" is set to the height value of current%coordinates in "data".done=0;%sets the variable "done" to zero. Done is an indicator showing if%a logical exression has been performed.if data((x-1),(y-1))>0 & data((x-1),(y-1))
