Hello guys,

I am unfamiliar with maple and have problems with dsolve complex system:

dz*_i/dt=sum(sum(z_i-z_j),j=1..2),i=1..2).

where i not equal to j and z* is conjugate(z).

here is my code:

for i from 1 to 2 do

summ(i)=0

od;

for j from 1 to 2 do

for i from 1 to 2 do

if i <> j then

summ(i)=summ(i)+(z_j(t)-z_i(t));

end if

od;

od

for j from 1 to 2 do

for i from 1 to 2 do

if j <> i then

ode_j={diff(conjugate(z_j(t)),t)-summ(i)=0,z_1(0)=I,z_2(0)=2*I}

dsolve(ode_j,numeric)

end if

od;

od;This gives me error in conjugate,missing differential equation.

How can I fix it, please help.
