how can I convert cell2mat when the values are numbers with different number of figures

Hi, I am trying to convert a 1828x1cell to a matrix so that I could make calculation with it.
The cell contains str in the form
'1'
'23'
'2'
'14'
When a try: data=cell2mat(d);
I get the following error:
_*Error using cat Dimensions of matrices being concatenated are not consistent.
Error in cell2mat (line 84)_ m{n} = cat(1,c{:,n});*
So, the problem is that in some case the number is one figure, like 1 and 2, but in other cases the number is two figures like 23 or 14.
Please, how can I solve this problem or what else can I do so that I can do some calculation with the values inside the cell?
Thanks

your problem is that the cell contains strings, and '1' and '23' does not have the same length, '23' is actually a 1x2 array of char. Therefor it cannot be placed in a matrix, it would work if u replaced '1' with eg '01'. If you are going to do calculations with these numbers i would recommand taking a look at "str2num" or "str2double".
Perhaps
data=cellfun(@str2num,d);
would solve your problem ?

@Kazi Shakib: then it seems that you tried to use str2double on a cell array of character vectors that do not represent numbers. If you want more help with this ask a new question, and upload your data in a .mat file by clicking the paperclip button.
