How do you vertically concatenate the rows of a cell array consisting of vectors of numbers?

I want to vertically concatenate the elements of a cell array so that, for example, an array that is 3 x 9 becomes 1 x 9. How do I do that? The following concatenates everything into one dimension, which isn't what I want:
vertcat(cellarray{:});

What you want to do is not clear to me. Can you upload the cell array (using the paperclip icon in the INSERT section of the toolbar), or perhaps just write code here to define an smaller (like 3x2) input, and what you expect the output to be?
The best method will likely depend on whether the cell elements are numeric, strings, character arrays, etc.

Example
m = magic(3);
m = [m,m,m];
cac = num2cell(m); % sample data
arrayfun( @(ix) vertcat(cac{:,ix}), [1:9], 'uni',false )
Is this what you look for?

Tru the following:
cellfun(@(x) cell2mat(x),num2cell(a,1),'uni',0)

Output = arrayfun(@(ColIdx) vertcat(YourCell{:,ColIdx}), 1:size(YourCell,2), 'uniform', 0);
