hi all,

m := 1+(-21+.7*I)*sqrt((2.3*6.494)*10^13-x^2)/(2.3*sqrt(((-21+.7*I)*6.494)*10^13-x^2))

fsolve(m = 0, x, {x = 10^7+26500*I .. 2*10^7+26600*I}, complex)

 

the above characteristic equation m=0 will give complex roots if we solve it. but fsolve is not able to solve this equation evenif i provided the range.through some light for my problem.

thanks
