According to your teachiing:
"if distanceApart < minAllowableDistanceApart

"
I have programmed it :
for i=1:200
a=data(i,:);
Index=find(a);
b=diff(Index);
c=find(b<5);
d=length(c);
if d==0
data(i,:)=a;
else
while d >= 1
for i=1:length(c)
if a(Index(c(i)))<=a(Index(c(i)+1))
a(Index(c(i)))=0;
else
a(Index(c(i)+1))=0;
end
end
Index=find(a);
b=diff(Index);
c=find(b<5);
end
data(i,:)=a;
end
end

Where data is a 200-by-500 matrix,but it does not work.Would you like to give me some advice about the codes I wrote?
Look forward to your letter.

I haven't folowed the discussion but you're suing the same looping index twice...
And don't use 'i' as the looping index at all cause its already used by matlab.
