Does anyone know that when I calculate magnitudes of a matrix with all complex numbers, why there are some NaN happening?

Because you are doing one of the operations listed on the NaN documentation that result in NaN values:
  • Any arithmetic operation on a NaN, such as sqrt(NaN)
  • Addition or subtraction, such as magnitude subtraction of infinities as (+Inf)+(-Inf)
  • Multiplication, such as 0*Inf
  • Division, such as 0/0 and Inf/Inf
  • Remainder, such as rem(x,y) where y is zero or x is infinity

Since I do not have your matrix, my guess is that there are NaN or Inf values in it.
