[Scilab-users] isreal question

[kjubo]

Dear all,

consider this code:

==start of code
clc
clear

a3 =  1
a2 = -1
a1 =  0.106865
a0 = -0.002212
mode(0)
sol = roots([a3 a2 a1 a0])
isreal(sol(1))
isreal(sol(2))
isreal(sol(3))
==end of code

i get this print in console:

  sol  = 

   0.8816333  
   0.0907062  
   0.0276605  
 ans  =

  F
 ans  =

  F
 ans  =

  F

I do not understand, why the isreal return false flag, if all roots are real
with no imaginary part.

I am missing something? Or it is bug?

using Scilab 6.0.2 x64

thank you

BR

J.K.
