Convert cell array to an array, when the size of the cells is different

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:

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{:})

thanks for the answer,

However, I don't want to have them all in the same row, but change them according to

the cell array. Imagine I have a cell array with 100 rows!

thanks

[madhan ravi]

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??

[Nikolas Spiliopoulos]

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
