Cumulative sum of cell array column

Hi

I have this cell array and I need to get the cumulative sum of column 7. Please help.

A =

Columns 1 through 3
  {1x39 cell}    {1x75 cell}    [ 7.669142585357160e-04]
  {1x75 cell}    {1x75 cell}    [-1.206232786783515e-04]
  {1x39 cell}    {1x41 cell}    [ 8.630787019556518e-04]
  {1x41 cell}    {1x65 cell}    [-2.445883525841570e-05]
  {1x65 cell}    {1x97 cell}    [ 9.109657363289406e-04]
Columns 4 through 6
  [-1.206232786783515e-04]    [3.231454899286823e-04]    [150]
  [     0.001808452047926]    [8.439143846238298e-04]    [-40]
  [-2.445883525841570e-05]    [4.193099333486180e-04]    [170]
  [ 9.109657363289406e-04]    [4.432534505352624e-04]    [-20]
  [-6.645138877833179e-04]    [1.232259242728113e-04]    [180]
Columns 7 through 11
  [ -40]    [ 55]    [1x1 sym]    [1x1 sym]    [1x1 sym]
  [ 330]    [145]    [1x1 sym]    [1x1 sym]    [1x1 sym]
  [ -20]    [ 75]    [1x1 sym]    [1x1 sym]    [1x1 sym]
  [ 180]    [ 80]    [1x1 sym]    [1x1 sym]    [1x1 sym]
  [-140]    [ 20]    [1x1 sym]    [1x1 sym]    [1x1 sym]

Answer 1

[Sophie]

Try this

res=sum(cellfun(@double,A(:,7)))
or
res=cumsum(cellfun(@double,A(:,7)))

Thank you so much, would you please help me to put this column vector in the first column of a S = cell(5,2)?

Answer 2

[James Tursa]

result = cumsum(vertcat(A{:,7}));

or

 result = sum(vertcat(A{:,7}));

depending on what you want.
