Hi all,
I have a cell array like this A={ [0 0 0 0] ; [1 1] ;[2] }
Is it possible to convert it in an array? I tried with cell2mat but I get an error because the sizes are different
thanks
Nikolas

Download padcat:
https://www.mathworks.com/matlabcentral/fileexchange/22909-padcat-varargin
and use it like this:
>> M = padcat(A{:})
M =
0 0 0 0
1 1 NaN NaN
2 NaN NaN NaN

[A{:}] % which is eqivalent to horzcat(A{:})

just give an example of your desired output in the example you gave! plus how can you put them in an array when the number of columns are different??

well it's from a for loop that the results are saved in A by using
A{i,1)=...
So for the example above I would like to get
B=[0 0 0 0; 1 1 0 0 ; 2 0 0 0 ]
So actyally putting zeros where the elements are less
