Hello mottelet
I tested it, residual results is ok
No it is not ok
as bellow shown;
-->dyke_error(p0,Value, i, y)
  ans  =
Nan
you have a "Not a Number" in first component
- 332.01567
   - 312.19667
   - 324.46484
   - 328.8238
   - 332.27738
   - 336.82964
   - 341.48485
   - 343.24755
   - 347.12254
   - 353.11492
   - 355.2301
   - 359.47381
   - 360.85216 ........ continue

but once I run leastsq function again, I got same results

-->[f,p,g]=leastsq(dyke_error,p0)
  g  =
Nan
     Nan
     Nan
     Nan
     Nan
  p  =
53.8
     1527.
     43.7
     55.7
     3424.7
  f  =
Nan

I still don't understand what's wrong with my code.

regards
karoli
