在 MATLAB Online 中打开

% Option 1
A = [-1-i;1+i]
A = 
  -1.0000 - 1.0000i
   1.0000 + 1.0000i
% option 2
B = [-1-1i;1+1i]  %1i is preferred
B = 
  -1.0000 - 1.0000i
   1.0000 + 1.0000i
% option 3
R = [-1 ; 1] ;  % real part 
I = [-1 ; 1] ;  % Imaginary part
C = R+1i*I
C = 
  -1.0000 - 1.0000i
   1.0000 + 1.0000i
