Hello everyone,
  I'm trying to fit data with the function and find two unknown parameters. I readlist the data from a text file.My data is as {Number,Number},{Number,Number},...I want to divide the first Number s to 10 and list again.What command do I have to use?Secondly, I use NonlinearRegress and it gives such an error:
  "The data argument of NonlinearRegress must be a matrix. Weighted regression is specified using the Weights option. The data format {{x11, x12, ..., {y11, ..., y1m}}, {x21, x22, ..., {y21, ..., y2m}}, ..., {{xn1, xn2, ..., {yn1, ..., ynm}}} is reserved for multiple response data, which will be supported in the future."
  What can I do to correct this error?
  Thank you very much.
  Fulya
