7 please answer fast and please use mathlab and include a copy code.. im using r2016b. Thanks

Answer 1

Note: The Question consists of multiple Sub parts. within the time alloted we solved maximum number of sub parts.

Solution 7 (a) function C - commutator (A, B) %commutator function sigmax and sigmay are passed as function parameters. %calculation. function. &End end Sample output ctave:17> commutator([0,1;1,0], [0, -1;i,0]) ans Solution 7 (b) function C-commutator (A, B) %commutator function. %sigma x and sigma z are passed as function parameters. Calculation. C = A*B - B*A; function. %End end Sample output octave:19> commutator([0,1;1,0], [1,0;0,-1]) Solution 7 (c) function C - commutator (A, B) %commutator function %sigma y and sigma z are passed as function parameters. %Calculation. %End end function. Sample output ctave: 21> commutator([0, -i;i,0], [1,0;0,-1]) ans =

Solution 7 (e) function C-anticommutator (A, B) %anticommutator function %sigmax and sigmax are passed as function parameters. %Calculation. %End end function. Sample output octave:26> anticommutator([0,1;1,0], [0,1;1,0]) ans Solution 7 (f) function C = anticommutator (A, B) %anticommutator function %sigmax and sigmay are passed as function parameters. Calculation. %End function. end Sample output octave:28> anticommutator([0,1;1,0], [e, -i;i,0]) ans

Executable Code

Commutator Function – Code

function C = commutator(A, B) %commutator function

%Calculation.

C = A*B - B*A;

%End function.

end

Anti Commutator Function – Code

function C = anticommutator(A, B) %anticommutator function

%Calculation.

C = A*B + B*A;

%End function.

end
