Selecting unique tracks to plot multiple lines in a figure?

I have a dataset of tracks and associated (x,y) points which are identified by a track ID, for ex.:

trackID, X, Y
1 45 75
1 50 80
1 55 85
3 10 30
3 15 35

I need to plot all these tracks (which all vary in number of points) on the same figure as individual lines. So far all I have is each track ID, is there a way to loop through and pull out each track's coordinates to put in a single plot?

[trackID,ia,ic] = unique(ds(:,1));

The dataset has 45000 points and I'm using Matlab 2011.

[Azzi Abdelmalek]

c1=A(:,1);
idx=unique(c1);
n=numel(idx);
c=cell(n,1);
for k=1:n
  c{k}=A(A(:,1)==idx(k),2:3);
end
c{1}
c{2}

This works perfect, thank you!!!

The loop solution...

u=unique(ds(:,1));
ix=u(1)==ds(:,1);   % find first set locations
plot(ds(ix,2),ds(ix,3))  % plot them
hold on                  % prep for remaining
for i=2:length(u)        % rest
  ix=u(i)==ds(:,1);
  plot(ds(ix,2),ds(ix,3))
end

Likely want to modify line colors, add legends, etc., but that's the gist of it...
