Show the code what you have tried , nobody will do the homework for you.

Answer 1

[MUTYALA NAGABABU]

j=sqrt(2);
y=[1+j*1 1+j*2
2+j*3 3+j*3];
v=[1+j*0
       1+j*3];
i=1;
n=2;
M = @(i) abs(v(i)) .* sum( abs(v(1:n)) .* abs(y(i,1:n)) .* cos(angle(y(i,1:n) + angle(y(1:n) - angle(y(i))))))

The above is the code i have tried.

Change

abs(v(1:n))

to

abs(reshape(v(1:n),1,[]))
