MATLAB: Adding the vectors at each cell in cell array

Question

Hi

I have a cell array where each cell contains a vector. I want to add up the vectors at each cell of each row.

The cell array is

M = cell(1,1) cell (1,2) ……..

cell(2,1) cell(2,2) …….

and so on

If we have the vector a_11 = [1 2 3 4 5] in cell(1,1) and a12 = [1,2,3,4,5] in cell(1,2), I want to add them so that the sum is [1+1 2+2 3+3 4+4 5+5] = [2 4 6 8 10]

then I want to store the result in a matrix whose rows is equal to the rows of the cell array, and columns equal to the length of the vectors (i.e. 5)

Could someone help me pleas?

Thanks
