From cell to matrix

I have a cell variable and need to extract its values.

The cell arrai is like in picture. I would like have a matrix or 3 vectors :

[ 5 6 5 12 6 12 ; 7 11 nan nan nan nan  ; 18 19 nan nan nan nan]      

(it is not important to have a nan value, i just need to extrcut togheter the informations

function cell2mat doesn't work because of cell dimension

Answer 1

[Matt J]

c(  cellfun('isempty',c) )  =  {[nan,nan]};

out=cell2mat(c),

Answer 2

[per isakson]

One way

%%
cac = { [5,6],[5,12],[6,12] ; [7,11],[],[] ; [18,19],[],[] }; % your sample data
ise = cellfun( @isempty, cac );
cac(ise) = {[nan,nan]};
M = cell2mat(cac);

Inspect M

>> M
M =
     5     6     5    12     6    12
     7    11   NaN   NaN   NaN   NaN
    18    19   NaN   NaN   NaN   NaN
