  • Method Details

    • binWidth

      double binWidth()
      Separation between points along x; should be uniform.
      Returns:
      a double.

    • getAllFxPoints

      double[] getAllFxPoints()
      Returns copy of the array of points f(x) to integrate (y-axis).
      Returns:
      an array of
      invalid reference 
      double
      objects.

    • getFxPoint

      double getFxPoint(int index)
      Point f(x) at index.
      Parameters:
      index - the index of the point to return.
      Returns:
      a double.

    • getX

      double[] getX()
      Returns copy of the array of points x (x-axis).
      Returns:
      an array of
      invalid reference 
      double
      objects.

    • halfWidthEnds

      boolean halfWidthEnds()
      Does this data set have half-width start/end bins. Intended for OST, where the first and last bins are half the regular width.
      Returns:
      a boolean.

    • lowerBound

      double lowerBound()
      Lower bound of the points along x.
      Returns:
      a double.

    • numPoints

      int numPoints()
      Number of points along x.
      Returns:
      the number of points.

    • upperBound

      double upperBound()
      Upper bound of the points along x.
      Returns:
      a double.
