MATLAB: Extracting certain values from a cell array with nth columns containing double arrays

cell arraysmatrix manipulationstructures

Hello all,

I have a 1×44 cell array where each column contains a 72×4 double array. For each of these double arrays I need to extract the maximum value within the 3rd column to a new matrix, therefore I should end up with a 44×1 double array. Any suggestions on how to do this would be appreciated. I have attached the .mat file if further clarification regarding the structure is needed.

Thanks in advance.

>>c = {[]};
>>class(c{1})
ans = double
>>isempty(c{1})
ans = 1

Or if you really want to be specific:

c = {double.empty(0)};
