• ptolemy.backtrack.automatic.ptolemy.math.Interpolation
  This class provides algorithms to do interpolation. Currently, zero, first, and third order interpolations are supported. These are the interpolation orders most often used in practice. zero order interpolation holds the last reference value; first order does linear interpolation; and third order interpolation is based on the Hermite curves in chapter 11 of "Computer Graphic, Principles and Practice", by Foley, van Dam, Feiner and Hughes, 2nd ed. in C, 1996.

  The setValues() method specifies the reference values as a double array. setIndexes() specifies the indexes of those values as an int array. These two arrays must have the same length, and the indexes must be increasing and non-negative; otherwise an exception will be thrown. The values are periodic if a positive period is set by setPeriod(). In this case, the period must be greater than the largest index, and values within the index range 0 to (period-1) are repeated indefinitely. If the period is zero, the values are not periodic, and the values outside the range of the indexes are considered to be 0.0. The interpolation order is set by setOrder().

  The default reference values are {1.0, 0.0} and the indexes are {0, 1}. The default period is 2 and the order is 0.
