How to assign label from one cell array to data inside another cell array?

14 views (last 30 days)
Hello everyone,
I have a 10*200 cell array C which each of these cells contains 1*1000 cell array.
I have another 10*200 cell array B which contains labels.
for example C{1,1} has label B{1,1}. I would like to assign label B{1,1} to each of 1000 cell array in cell C{1,1}. How can I do that? I would like to creat a function, and then apply this function to each cell array of C using cellfun. Any help would be greatly appreciated!

would be easier if you provide an example with small size to explain the input and output

Thanks for your reply. Sure, here is an example with small size
C = {ones(4,5), 2*ones(4,5), 3*ones(4,5); 4*ones(4,5), 5*ones(4,5), 6*ones(4,5)};
B = {7, 8, 9 ; 10, 11, 12};
I'm using the following code to put each column of the matrix in C{i,j} to one cell
E = cellfun(@(x) mat2cell(x,size(x,1),ones(1,size(x,2))), C, 'UniformOutput',false)
Now, E is a 2*3 cell array and E{1,1} is a 1*5 cell array. I would like to assign B{1,1}, i.e., 7 to each of these 1*5 cell arrays in E{1,1} and so on. In other words B{1,1} is the label of each of 5 cells in E{1,1}. Please let me know if it makes sense now.

Don't be obsessed with cellfun(). A simple for-loop will do
%%
C = {ones(4,5), 2*ones(4,5), 3*ones(4,5); 4*ones(4,5), 5*ones(4,5), 6*ones(4,5)};
B = {7, 8, 9 ; 10, 11, 12};
for k=1:numel(C)
C{k}(:)=B{k};
end
This answers your original question. Maybe then you can apply E=cellfun() in your note.
