Having trouble understanding some code

[col,row]=size(bw);
prj=zeros(col,1);
for i=1:col
for j=1:row
if bw(i,j)==0
prj(i)=prj(i)+1;
end
plot(prj(i));
end
end
The above code is to do a horizontal projection on an image, however, I am not sure how it works and I try to make a plot for the nested loop to get a better understanding but its crashing my computer. Any one kind enough to share some insight into how this works? Help much appreciated, thanks.
