% suppose a fake matrix with size 3x3
>> A = rand(3);
A =

    0.7922    0.0357    0.6787
    0.9595    0.8491    0.7577
    0.6557    0.9340    0.7431
% assign a complex value at loation (1, 1)
>> A(1, 1) = 1+1i;
A =

   1.0000 + 1.0000i   0.0357 + 0.0000i   0.6787 + 0.0000i
   0.9595 + 0.0000i   0.8491 + 0.0000i   0.7577 + 0.0000i
   0.6557 + 0.0000i   0.9340 + 0.0000i   0.7431 + 0.0000i
