group every ten cell array
显示 更早的评论
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?

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

Yeah, I can help with that. I see that each element is a row vector of varying length. Do you want to concatenate them horizontally (example 1 below) or vertically (example 2 below)?
% Example 1
a = [1 2 3 4];
b = [5 6 7 8 9 10 11];
result = [1 2 3 4 5 6 7 8 9 10 11];
% Example 2
result = [ 1 2 3 4 nan nan nan;
5 6 7 8 9 10 11 ];

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
