How to add NaN in cell before last one

Dear all,

i have a cell with different sizes

a{1} = [1 2 3 4 5 10];
a{2} = [2 2 4 5 10];
a{3} = [8 2 10];
a{4} = [8 2 9 9 2 1 3 10];

one row, 4 columns,

number 10 represent (label or number of class) of each one,

v = cellfun('size',a,2);
r = numel(a);
M = NaN(r,max(v));
for k = 1:r
  M(k,1:v(k)) = a{k};
end

this for loop to find max and make the cell equal before change it to matrix, the problem is NaN added after last number which 10,

M =

1 2 3 4 5 10 NaN NaN

2 2 4 5 10 NaN NaN NaN

8 2 10 NaN NaN NaN NaN NaN

8 2 9 9 2 1 3 10

is there a way to add NaN before label 10 and make it equal as well?

thanks in advnace

a{1} = [1 2 3 4 5 10];
a{2} = [2 2 4 5 10];
a{3} = [8 2 10];
a{4} = [8 2 9 9 2 1 3 10];

v = cellfun('size',a,2);
r = numel(a);
M = NaN(r,max(v));
for k = 1:r
  M(k,1:v(k)-1) = a{k}(1:end-1);
  M(k,end) = a{k}(end) ;
end
