Constructor Summary

Gridded2DSet(MathType type, float[][] samples, int lengthX)
a 2-D set with manifold dimension = 1, with null errors, CoordinateSystem and Units are defaults from type

Gridded2DSet(MathType type, float[][] samples, int lengthX, CoordinateSystem coord_sys, Unit[] units, ErrorEstimate[] errors)
a 2-D set with manifold dimension = 1; samples array is organized float[2][number_of_samples] where lengthX = number_of_samples; no geometric constraint on samples; coordinate_system and units must be compatible with defaults for type, or may be null; errors may be null

Gridded2DSet(MathType type, float[][] samples, int lengthX, CoordinateSystem coord_sys, Unit[] units, ErrorEstimate[] errors, boolean copy)

Gridded2DSet(MathType type, float[][] samples, int lengthX, int lengthY)
a 2-D set whose topology is a lengthX x lengthY grid, with null errors, CoordinateSystem and Units are defaults from type

Gridded2DSet(MathType type, float[][] samples, int lengthX, int lengthY, CoordinateSystem coord_sys, Unit[] units, ErrorEstimate[] errors)
a 2-D set whose topology is a lengthX x lengthY grid; samples array is organized float[2][number_of_samples] where lengthX * lengthY = number_of_samples; samples must form a non-degenerate 2-D grid (no bow-tie-shaped grid boxes); the X component increases fastest in the second index of samples; coordinate_system and units must be compatible with defaults for type, or may be null; errors may be null
