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





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?

 Accepted answer

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".



would solve your problem ?

Thanks, it worked!

Thank you very much! This answer was very helpful!

data = str2double(d);

would work as well if d is a cell array of strings.
