Just as other number,
mat=[1 2 2+3i;4 5 7;6 10 2]

% 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
