Sum of cell array columns

i am faced with a probelm of having a cell array of 7x50 size. where each cell consists of twenty rows and seven columns and I have to sum this cell array to recive a 7x50 output of 20 rows and one column each. this input cell array is titled as XX.

%the XX is of the following size
20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double	20x7 double

Using cellfun, it is a one-liner.

XX % 7x50 cell array
XX_new = cellfun(@(x) {sum(x,2)}, XX);

[Muhammad Jawad Sajid]

Thanks. After executing the above code the following message appears: Undefined function or variable 'C'.

[madhan ravi]

C is your cell array.

 XX_new = cellfun(@(x) {sum(x)}, cell_array);

[Muhammad Jawad Sajid]

Thanks for the clarification. Any idea on how to use this newly generated array as an input to a function.

[Ameer Hamza]

yes, I meant to write XX in the question instead of C. You can just input a cell array to a function by its variable name.
