Hi,
For your data, converting into xls or xlsx would be easier. If you'd need only csv, then you'd need to use the syntax as this one:
Data = load('TestingTDStatic1.mat');
csvwrite('CSVDATA_Index.csv', Data.TestIndex); % 1st csv file
for ii=1:36 % given 36 sets of structure type of data size in ROI
% 2nd csv file
csvwrite('CSVDATA_ROI.csv', Data.ROI{1, ii}.Xaddress', Data.ROI{1, ii}.Yaddress'); % similarly for Polarity, TimeStamp
end
