I'm trying to solve a system of coupled equations where the results are expected to be complex. The problem is that I want only the solutions that fall in range [-i,i], when I put this condition, I got error about invalid comparison of complexes. Is there any way to put this condition on the obtained solutions.
What do you mean by "range [-i,i]"? Is that the segment between the points -i and i in the complex plane? Then the conditions should be Re[variable]==0&&-1<=Im[variable]<=1.
I meant the real and imaginary parts should be ranged between -1 and 1
I tried to define the conditions as
-1<Re<1 , -1<Im<1 but I got this error
NSolve::precbd: Requested precision [DoubleStruckCapitalC] is not a machine-sized real number between
$MinPrecision and $MaxPrecision.
The problem is solved.
Thanks for your help
