Cell arrays with a vector within a cell within a cell

I have a cell array where each element consists of a 1 x 1 cell containing a vector of type double, i.e., C{1,1} contains a vector of length N.
How do I convert the inner cells from 1 x 1 cells into N x 1 cells where the entries correspond to each vector of length N? The N of each vector might be different.
I think the right way to do this is via cellfun but something like
C_out = cellfun(@(C_test) num2cell(C_test{1}), C_in, 'uniform',0);
does not quite get me there.

Maybe this is what you mean?
C_in = 1×3 cell array
{3×1 double} {2×1 double} {[6]}
C_out=num2cell(cell2mat( cellfun(@(x) cpad(x,n), C_in,'uni',0) ) )
C_out = 3×3 cell array
{[1]} {[ 4]} {[ 6]} {[2]} {[ 5]} {[NaN]} {[3]} {[NaN]} {[NaN]}
function C=cpad(C,n)

cellfun up a num2cell call.

What does "cellfun up" mean? I think that's what I tried to do as I mention in my question.
