format shortG
D = [0.2352 0.5263]
D = 1×2
       0.2352       0.5263
D = round(D(:),3) - [0.005 0.006].'
D = 2×1
         0.23
         0.52

在 MATLAB Online 中打开

D = [0.2352, 0.5263];
d = floor(D*100)/100;
%version 1
fprintf('D = '); fprintf('%.2f, ', d(1:end-1)); fprintf('%.2f\n', d(end));  %must be one line for LiveScript
D = 0.23, 0.52
%version 2
disp("D = " + strjoin(compose("%.2f", d), ', '))
D = 0.23, 0.52
