Combining Data from different Cells in a cell array

So I've been hunting through the answer community, and I have yet to find what I'm looking for. What I'm attempting to do is combine 2 cell arrays so that the cells actually merge together, without using a for loop. What I have are two large cell arrays, one that contains the x coordinates and another that contains the y coordinates. I would like to put them together so that each cell contains both the x and y in two serperate columns.

For example

xcoordinate = {[1;2;3],[3;4;5;6]}   %cell array with column vectors in each cell

ycoordinate = {[8;9;10],[12;16;17;10]}   %cell array with column vectors in each cell

What I would like the product to be Without using a For loop is:

XYcoordinates = {[1 8;
                  2 9; 
                  3 10]
                  [3 12;
                   4 16;
                   5 17;
                   6 10]}

It needs to be in this format with the [x y] sitting next to each other for a function I want to use with cellfun. If you have any suggestions, I would greatly appreciate it. Thanks!

Why do you want to avoid a FOR loop? Most likely the the cellfun appraoch is slower, so I do not see the benefit.

cellfun(@(x,y) [x y],xcoordinate',ycoordinate','un',0)

Awesome. I knew it had to be something simple like this, but I completely missed this solution. It does exactly what I wanted it to do. Thanks!

Why do you want to avoid a FOR loop? Most likely the the cellfun approach is slower, so I do not see the benefit. So compare the speed:

XYCoordinate = cell(size(xcoordinate));
for iC = 1:numel(xcoordinate)
  XYCoordinate{iC} = [xcoordinate{iC}, ycoordinate{iC}];
end
