Hi,
In my loop operation I am generating 1 X 72 cell. At every iteration the values will be stored in the consequetive columns in the form of 8 x 3 double. However, in some cases it is 5 x3 or 2 x3. I would like to make all entries in the form of 8 x 3.. Could someone please help me with this ..
I have attached my matrix for an reference..

result = cellfun(@(C) full([(0:7).', sparse(C(:,[1 1])+1, [1*ones(1,size(C,1)), 2*ones(1,size(C,1))], C(:,[2 3]), 8, 2)]), Data, 'uniform', 0);

mask = cellfun(@isempty, Data));
result(mask) = {[(0:7).', zeros(8,2)]};
result(~mask) = cellfun(@(C) full([(0:7).', sparse(C(:,[1 1])+1, [1*ones(1,size(C,1)), 2*ones(1,size(C,1))], C(:,[2 3]), 8, 2)]), Data(~mask), 'uniform', 0);

May try the following to add NaN to the new rows
load('data.mat');
addrow = cellfun(@(x) 8-size(x,1),Data,'uni',0);
result = cellfun(@(x,y) vertcat(x,NaN(y,3)),Data,addrow,'uni',0);

Hi,
Many thanks.. The only isssue is , in the 8 x 3 array the first columns should be always 0 1 2 3 4 5 6 7... For other 2, 3 columns NaN entries is not a problem..
Is there a way out??
