To extract specific columns (in your case, columns 1 and 3) from a cell array and obtain all rows, you can use MATLAB's cell array indexing. Given that fds.data is a cell array with dimensions {178093×3}, you can extract the desired columns as follows:
% Extract all rows but only columns 1 and 3
extractedData = fds.data(:, [1, 3]);
% Display the size of the extracted data to confirm
disp(size(extractedData));
% Display the first few rows of the extracted data to verify
disp(extractedData(1:5, :));
