How do I create multiple column vectors from one big column vector?

I have two column vectors, objx and objy, both of which contain 20,160 floats. I need to dice it up every 48 iterations to create voronoi figures. There will be 420 voronoi diagrams. How do I go about creating smaller vectors each of which containg 48 floats each to create these voronoi diagrams?

That's clear. The comma in 20,160 threw me off. There's no need to use a comma unless the number of digits is very large.

Try this
X = reshape(objx, 48, 420); % X is 48*420
Y = reshape(objy, 48, 420); % Y is 48*420
% loop will run 420 times
for i=1:size(X,2)
x = X(:,i); % x is 48*1
y = Y(:,i); % y is 48*1
voronoi(x,y);
% save the voronoi diagram
end

That's true; a col or row vector will result in the same reshape. My mind may have still been on the possibility of cell arrays converted to matrices.
