Sum up a value to a row and create new colum at the end of the cell

How can I add to a row 1 unit? I have the following cell:

A= {12 1996 1999
15 1999 2002
26 1997 2001
43 1999 2008
59 1995 2000}

I would like the output to be:

Output={A= {12 1996 1999 2000
15 1999 2002 2003
26 1997 2001 2004
43 1999 2008 2009
59 1995 2000 2001}

I tried this:

A(:,end+1) = cell2mat(A(:,3))+1;

It gives me the error: 'Conversion to cell from double is not possible.'

But if I take out the 'cell2mat', I get the error: 'Undefined function 'plus' for input arguments of type 'cell'.'

Does someone know how to solve the problem? Thank you

Answer 1

[Azzi Abdelmalek]

cell2mat(cellfun(@(x) [x x+1],A,'un',0))

%or

[A num2cell([A{:}]+1)']

ok I omited the part that I have more rows that I presented in the example. I believe that's why the codes are not working. I will edit. Sorry

thanks, it works perfectly like this!

A=[A num2cell([A{:,3}]+1)'];

A(:,end+1) =cellfun(@(x)x+1,A(:,end),'un',0)
