[SciPy-User] [SciPy-user] Error using fmin

[RDX]

I am using fmin and it returns initial guess as the final solution.   

def Traug (v): 
    err=0 
    Traug_RHOB = v[0] + v[1]*(z_den_s/3125.0)**v[2] 
    count =arange(size(den_s)) 
    for i in count: 
        err += abs(den_s[i] - Traug_RHOB [i]) 
    return err 

vO=[1.6, 0.5, 0.35] 
t=fmin(Traug,vO ) 
a=t[0]; b=t[1]; c=t[2]; 

Code gives me a=1.6, b=0.5, c=0.35, which is my initial guess. 

What is wrong? Many thanks in advance. 

Regards,
Rishi
