Input:
a = cell(3,1);
a{1,1} = [1 2 3];
a{2,1} = [1 2 3 4];
a{3,1} = [1 2 3 4 5];
Desired output:
b = [[1 2 3 0 0];[1 2 3 4 0];[1 2 3 4 5]];
What would be the best way to get this output from this input?

Jonathan - one way would be to use cellfun to apply a function to each element of your cell array padding each with zeros so that all arrays are of the same length. For example, we can get the maximum length as
maxLength = max(cellfun(@(x)length(x),a));
We would then use cellfun again to pad the arrays with zeros using repmat (which just repeats a matrix) as
aPadded = cellfun(@(x)[x repmat(0,1, maxLength - length(x))],a,'UniformOutput',false);
b = cell2mat(aPadded);
Try the above and see what happens!
