Question: Warning when solving equation

Hi all,

 

I tried to find the real solution of the unlinear integral equation:

 

exp(-h^2/T)*(Int(exp(-x^2/T)*BesselI(0, h*x/T)*x, x = 0 .. 1))/T

 

but I got the warning and an complex solution:

 

 solve(subs(T = 1, eq)-.99 = 0, h)

Warning, solutions may have been lost

-1.232350242*10^(-32)-1.130417828*I

 

Can anyone help me to find a real solution for this issue (if possible)...?

I would like to thank you in advance.
