differential equations – How can I correct this code to get an answer?


I need to calculate matrix m1 according to following algorithm.
Then, I have to put it in the differential equation.
However, matrix m1 is complex and therefore the differential equation does not work.
How can I correct this code to get an answer?

 m = {{0, WP(t), WP(t), WP(t), 0}, {WP(t), -FSR, 0, 0, -WS(t)}, {WP(t),
 0, 0, 0, WS(t)}, {WP(t), 0, 0, FSR, -WS(t)}, {0, -WS(t), 
 WS(t), -WS(t), 0}};

 q = Eigenvectors(m);
qq1 = Normalize(q((1)));
qq2 = Normalize(q((2)));
qq3 = Normalize(q((3)));
qq4 = Normalize(q((4)));
qq5 = Normalize(q((5)));

 Ali1 = {{D(qq1, t)((1)), 0, 0, 0, 0}, {D(qq1, t)((2)), 0, 0, 0, 
  0}, {D(qq1, t)((3)), 0, 0, 0, 0}, {D(qq1, t)((4)), 0, 0, 0, 
  0}, {D(qq1, t)((5)), 0, 0, 0, 0}};
 Vali1 = ConjugateTranspose(Ali1);
 Kazi1 = Ali1.Vali1;

 Ali2 = {{D(qq2, t)((1)), 0, 0, 0, 0}, {D(qq2, t)((2)), 0, 0, 0, 
  0}, {D(qq2, t)((3)), 0, 0, 0, 0}, {D(qq2, t)((4)), 0, 0, 0, 
  0}, {D(qq2, t)((5)), 0, 0, 0, 0}};
Vali2 = ConjugateTranspose(Ali2);
Kazi2 = Ali2.Vali2;

Ali3 = {{D(qq3, t)((1)), 0, 0, 0, 0}, {D(qq3, t)((2)), 0, 0, 0, 
0}, {D(qq3, t)((3)), 0, 0, 0, 0}, {D(qq3, t)((4)), 0, 0, 0, 
0}, {D(qq3, t)((5)), 0, 0, 0, 0}};
Vali3 = ConjugateTranspose(Ali3);
Kazi3 = Ali3.Vali3;

Ali4 = {{D(qq4, t)((1)), 0, 0, 0, 0}, {D(qq4, t)((2)), 0, 0, 0, 
0}, {D(qq4, t)((3)), 0, 0, 0, 0}, {D(qq4, t)((4)), 0, 0, 0, 
0}, {D(qq4, t)((5)), 0, 0, 0, 0}};
Vali4 = ConjugateTranspose(Ali4);
Kazi4 = Ali4.Vali4;

 Ali5 = {{D(qq5, t)((1)), 0, 0, 0, 0}, {D(qq5, t)((2)), 0, 0, 0, 
 0}, {D(qq5, t)((3)), 0, 0, 0, 0}, {D(qq5, t)((4)), 0, 0, 0, 
  0}, {D(qq5, t)((5)), 0, 0, 0, 0}};
 Vali5 = ConjugateTranspose(Ali5);
 Kazi5 = Ali5.Vali5;


m1 = Kazi1 + Kazi2 + Kazi3 + Kazi4 + Kazi5;

 sol1 = NDSolve({D(c(t), t) == (m1).c(t),
 c(0) == {1, 0, 0, 0, 0}}, c, {t, 0, 2 tf});

 ans = Evaluate(c(t) /. sol1((1)))((5));
 ans1 = Abs(ans)^2;
 Plot(ans1, {t, 0, 2 tf}, Frame -> True) 

Hi friends, I need to calculate matrix m1 according to following algorithm.
Then, I have to put it in the differential equation.
However, matrix m1 is complex and therefore the differential equation does not work.
