Hi all i have a cell array 1x180 and i want to group by every 10 cells

For example i want the elements from 1 cell till 10 get grouped,11:21, 22:32 etc..

So the new cell should be 1x18

How can i do this?

在 MATLAB Online 中打开

c = cell(1,180);  % the original 1x180 cell array
newCell = mat2cell(c,1,repmat(10,1,18)); %the new nested cell array

Yeah, you can still concatenate them vertically but you'd need to pad the shorter vectors. Here are both methods:

Concatenate horizontally

newCellMerge = cellfun(@(x)[x{:}],newCell, 'UniformOutput', false);

Concatenate vertically, pad with NaN values at the end of short vectors

newCellMerge = cell(size(newCell)); 
for i = 1:length(newCell)
    len = cellfun(@length, newCell{i});
    cellPad = cellfun(@(x,y)padarray(x',y,NaN,'post')',newCell{i}, num2cell(max(len)-len),'UniformOutput',false)';
    newCellMerge{i} = cell2mat(cellPad); 
end
