i hv cell array of a large size and every cell contains different no. of elements. how to convert this into a 3d array. e.g. with 7x2 cell array:

    array= {0,[11,12];[13,29],[2,5,6,8];0,[11,35,17];19,[12,6,29];33,[11,3,5,17];0,[11,7];[3,3],[5,1]}

3d array can look like this:

    output(1,:,1)=0
    output(1,:,2)=[11,12]
    output(2,:,1)=[13,29]
    output(2,:,2)=[2,5,6,8]
    output(3,:,1)=0
    output(3,:,2)=[11,35,17]

and same for all other rows. (1st value before semicolon is from 1st slice and 2nd is from 2nd slice)

Thanks.

"3d array can look like this:"

No, it can't. MATLAB does not support ragged arrays (because they are not a useful mathematical concept).

Ok is there any other way to convert this into 3d?
