      Curve fit program. Polynomial, exponential, power law.


Calling Sequence

      fit, x, y, [cur]


      x,y = input curve data arrays. in

Keyword Parameters


      cur = optional description of the last fit done. out
          cur has following format:
          cur = [FTYPE, XOFF, YOFF, NDEG, C0, C1, ..., Cn]
                for polynomial,
          cur = [FTYPE, XOFF, YOFF, A, B]
                for exponential and power law.
          Useful for generating data using the fitted curve
          by calling y = gen_fit( x, cur)
          where x and cur are inputs, y is generated output.
