public class Irregular1DSet
- extends IrregularSet
Irregular1DSet represents a finite set of samples of R.
Note that Irregular1DSet reorders samples given in the
constructor; to convert between values and indices,
always use the methods valueToIndex and indexToValue.

Constructor Summary |
Irregular1DSet(MathType type,
float[][] samples)
a 1-D irregular set with null errors, CoordinateSystem
and Units are defaults from type |
Irregular1DSet(MathType type,
float[][] samples,
CoordinateSystem coord_sys,
Unit[] units,
ErrorEstimate[] errors)
a 1-D irregular set; samples array is organized
float[1][number_of_samples]; samples need not be
sorted - the constructor sorts samples to define
a 1-D "triangulation";
coordinate_system and units must be compatible with
defaults for type, or may be null; errors may be null |
