hi
I have an empty cell array
Let call it W
At the output It must have a cell array with two columns and n rows
Each element of columns is an array with variable length
I wanna write at the end of arrays in columns
How can access the last element of that arrays in the cells
for example W(1,2) end+1 i.e At the end of an array at the second column of first row

W{1,2}(1,end+1)
But first, define your empty cell array as follows:
W = cell(2,2);

I wish I could ask you for help with any questions I may have in the future Of course, from a faster method other than this website

To access the last element of an array stored in cell array C at location {m,n},
y = C{m,n}(end);
To access the last element of all cells stored in cell array C,
y = cellfun(@(x)x(end),C);
Update
To append a value to the end of the vector stored in cell array C at location {m,n},
C{m,n}(end+1) = x;
To append a value M(m,n) in matrix M to the end of the vector stored in cell C{m,n},
C = reshape(arrayfun(@(i){[C{i}, M(i)]},1:numel(C)),size(C));
Demo:
C = reshape(arrayfun(@(i){rand(1,randi(100))},1:100),50,2); % original values
M = reshape(1:100,50,2); % values to append
C2 = reshape(arrayfun(@(i){[C{i}, M(i)]},1:numel(C)),size(C));
