Hi all,
I have nested cell array where each cell array contains a time series.
How do I write the contents of each of the cell array into rows in excel in the same sheet?
Like for example i want WS {2,1} to be written to the 2nd row in excel in the same sheet.

for old version of MATLAB
n = cellfun(@numel,WC);
k = cumsum(n);
ii = k - n + 1;
v = ones(k(end),1);
v(ii(2:end)) = v(ii(2:end)) - n(1:end-1);
A = accumarray([repelem((1:numel(n))',n),cumsum(v)],[C{:}]',[],[],nan);
xlswrite('yourxlsxfile.xlsx',A);

Since all aren't same size, the trivial solution of
xlswrite(cell2mat(WS))
is out unless you augment the shorter to the length of longest.
If doing that is out, you'll have to either loop or use cellfun to write each array element.

The problem starts with the different sizes of each rpw which makes it more complecated to unravel the nested cell arrays
c = {{1 2 3}; {1 2 3 4}; {1 2 3}};
% check row sizes
sizes = cellfun('length', c);
maxlen = max(sizes);
% equalize row sizes
for i = 1:numel(c)
c{i} = [c{i} cell(1,maxlen-sizes(i))];
end
% unravel cell array into a 2d cell array
c1 = vertcat(c{:});
% now you can export it easily
writecell(c1, 'c.xlsx', 'sheet', 1)
