Transform a 3D dimension array to n 2D matrix
显示 更早的评论
How can I transform a 3D dimension array (15*781*81) to 15 extracted 781*81 2D matrix to make it feasible to write down them in different Excel files?
Cheers,
Hiua

result = cellfun(@squeeze, num2cell(YourArray, [2 3]), 'uniform', 0)
This will give you a 15 x 1 cell array, each entry of which is a 781 x 81 array

Another possible way:
result = arrayfun(@(k) squeeze(YourArray(k,:,:)),1:15,'UniformOutput',false);
This will also give you the same result as Walter-san's answer.

There is no point in creating a separate cell array with duplicates of all of the data.
Simply loop over the array and save it as you go:
A = your 15x781x81 array
for k = 1:size(A,1)
M = permute(A(k,:,:),[2,3,1]);
... save M here
end
