hi all y teachers,

i have a cell :

a = {{8x1cell} {14x1cell} {11x1cell} {23x1cell} {17x1cell} {8x1cell} {18x1cell} {14x1cell} {20x1cell} {28x1cell}}

i need to change the dimension of each cell to a fix number, say 50x1 cell. So each cell will have dimension 50x1, and i want the rest rows of the cell to be 0 or []

ex: take the 1st col of the cell, it's 8x1cell and i need it to be 50x1 with 42rows left to be zero or []

old 8x1cell = {'i'; 'need'; 'a'; 'glass'; 'of'; 'water'; 'right'; 'now'}

new 8x1cell = {{'i'; 'need'; 'a'; 'glass'; 'of'; 'water'; 'right'; 'now'; 0; 0; ... till row 50}

is there any possible way i can perform that? really need your helps, plzz! :(

thx,

Maya

Hello there, lets say I have the cell array

1×6 cell array
    {8791×1 double}    {8782×1 double}    {8802×1 double}    {8795×1 double}    {8806×1 double}    {8791×1 double}

I need to change all of them to be

{8782×1 double}

So that I would have a 1×6 cell array where there is repeated {8782×1 double}

Wuaaaaa,, its work! the answers you both give me are working exactly what i need,, i've just checked and it's so simple,, stupid me. sorry for bothering you with this low-level question.. :D

So many thanks for you Mr Simon and Mr Jiang.

Ouw,, may i asked 1 more low-level question?

Is it possible to make that cell array (a) as output in a function?? 'coz i need to call a function containing that cell as an output..
