MATLAB怎么输出空格

x = 3.14159;
y = 2.71828;

disp(['x = ', num2str(x), '  y = ', num2str(y)]);

x = 3.14159  y = 2.71828

x = 3.14159;
y = 2.71828;

output = sprintf('x = %0.4f   y = %0.4f', x, y);
disp(output);

x = 3.1416   y = 2.7183

data = [1, 2, 3, 4, 5];

disp(data);
disp('---------------------');
disp(data, '  ');

     1     2     3     4     5

---------------------

     1 2 3 4 5

for i=1:5

    disp(['Current index: ', num2str(i)]);

end

Current index: 1
Current index: 2
Current index: 3
Current index: 4
Current index: 5
