在 MATLAB Online 中打开

datacell = get(handles.YourTable, 'Data');
datamatrix = cell2mat(datacell(:,1:end-1));
sums = sum(datamatrix, 2);
sumscell = num2cell(sums);
datacell(:,end) = sumscell;
set(handles.YourTable, 'Data', datacell);

It seems as if it was adding the ASCII numbers together.

Nevermind, i fixed it, i used:

result = reshape(str2num(datamatrix(:)), size(datamatrix));

to convert number character array to a number integer array. Once that was done, sums = sum(result,2) worked just fine.
