Hi friends,
i have a matrix with cell (88 * 1), every row has a matrix with 30*768*20 double, where 20 is an (epochs).
I want to reconcatinate it to separted epoches (30*1), so for first row will be reconcatinated to 20 *88 *768 times of (30*1).
the final matrix will 1351680*1
I have tried it manually, but it's going to take a long time, but i believe its going to be easy using for loops.
for i= 1:20
for s=1:88
for d=1:768
O1=squeeze(XTrain{s,1}(:,:,i));
G= O1 (:,d);
end
end
end
O={G};

Something like this. Look for function reshape().
O=XTrain;
for s=1:88
O{s}=reshape(XTrain{s},x,y,z);
end

Follow this example, play out how you want to flat the matrix, use shiftdim() if needed
%%
XTrain=repmat({rand(3,7,2)},8,1);
Out=cell2mat(XTrain');
Out=reshape(Out,3,[]);
Out=Out';
Out=mat2cell(Out,ones(1,112),3);
