How to efficiently: Access and store row of cell value

Dear Coder, The objective was to access value in a row of cell and transfer it to other structure. Is there other efficient way than using for loop as shown below.

   for i = 1:2650
  feature_set (i,1) = Patient.sub_band{i, 1}.feature; end

Thanks in advance for the insight.

Are you looking for something like this?

%%create a radnom sturcutre
for i = 1:2650
    Patient.sub_band{i, 1}.feature = rand; 
end
% Now extract 
all_features = [Patient.sub_band{:}] ;
 feature_set = [all_features(:).feature] ;

Dear KSVV, thanks for the proposed technique, indeed it is efficient then the for loop. For example, the time taken to process the data using FOR-LOOP and your-approach is 0.01050 sec and 0.00650 sec, respectively. In addition, your line is more tidy if the more DOT FEATURES are to be processess.

Thank you
