How To Write Long Plot Handle

My code has the plot handle shown below that is used with 'plot3.' Seventeen different data sets (i.e., n=17) are being plotted together. The problem is that I need to use this syntax for plots of other sizes (e.g., n=6, n=12, n=<fill in the blank>, etc.) and don't want to write it out individually each time. Can this syntax be generated on-the-fly somehow? In other words, is there some way to run a FOR loop that will write this out, appending it for each loop until n has been reached, and then issue plot3 with it?
h1=plot3(coll{1}(:,1),coll{1}(:,2),coll{1}(:,3),coll{2}(:,1),coll{2}(:,2),coll{2}(:,3),...
coll{3}(:,1),coll{3}(:,2),coll{3}(:,3),coll{4}(:,1),coll{4}(:,2),coll{4}(:,3),...
coll{5}(:,1),coll{5}(:,2),coll{5}(:,3),coll{6}(:,1),coll{6}(:,2),coll{6}(:,3),...
coll{7}(:,1),coll{7}(:,2),coll{7}(:,3),coll{8}(:,1),coll{8}(:,2),coll{8}(:,3),...
coll{9}(:,1),coll{9}(:,2),coll{9}(:,3),coll{10}(:,1),coll{10}(:,2),coll{10}(:,3),...
coll{11}(:,1),coll{11}(:,2),coll{11}(:,3),coll{12}(:,1),coll{12}(:,2),coll{12}(:,3),...
coll{13}(:,1),coll{13}(:,2),coll{13}(:,3),coll{14}(:,1),coll{14}(:,2),coll{14}(:,3),...
coll{15}(:,1),coll{15}(:,2),coll{15}(:,3),coll{16}(:,1),coll{16}(:,2),coll{16}(:,3),...
coll{17}(:,1),coll{17}(:,2),coll{17}(:,3));
Thanks in advance,

The usage of the term "handle" is not clear here.

My apologies. The Help documentation often refers to the them as "handles" and that's where I gleaned it from. "Handle" here refers to "h1." It's merely a pointer (i.e., handle) for the plot. Later when setting other plot preferences, certain commands (e.g., 'set') references the handle to implement the commands. Hopefully that clears it up a bit.

What about:
axes('NextPlot', 'add'); % or : hold('oll')
h = gobject(1, n);
for k = 1:n
h(k) = plot3(coll{k}(:,1), coll{k}(:,2), coll{k}(:,3));
end
