Re: Possible bug?

Dear Olaf,

Thanks for your response.

The function F is the Physic Model that I am try to use, so I can´t change. 

I try the following 

[P, funcion, cvg] = nonlin_curvefit (F, pin, x, y);
with
pin=[359;58337;1.1;0.9;400;150000;1.1;0.9;460;170000;1.1;0.9; 525; 62456;
1.1;0.9]

and I have the same problem.

error: weighted residuals are not real

Looking in the debug mode, I found that 

  f = F (p);
        r = wt .* f;
        r = r(:);
**        if (~isreal (r))
          error ("weighted residuals are not real");
        endif

but if I look in **

but 
r =

  -7234.132 +    0.000i
  -6749.209 +    0.000i
  -6268.353 +    0.000i
  -5526.880 +    0.000i
  -4790.524 +    0.000i
  -3608.309 +    0.000i
  -2227.055 +    0.000i
.....
Could you help me?

Mauricio
