********************************************************************************
Changes that were made in July 2006 by Joshua Reich I.
********************************************************************************
Code Cleanup:
Update the calling convention for all external facing functions. By
external
facing, I mean all functions that are directly referenced in cube.sql.
Prior
to my update, all functions used the older V0 calling convention. They now
use V1.
New Functions:
cube(float[]), which makes a zero volume cube from a float array
cube(float[], float[]), which allows the user to create a cube from
two float arrays; one for the upper right and one for the lower left
coordinate.
cube_subset(cube, int4[]), to allow you to reorder or choose a subset of
dimensions from a cube, using index values specified in the array.

This makes a one dimensional cube.
cube(1,2) == '(1),(2)'
+ cube(float8[]) returns cube
+ This makes a zero-volume cube using the coordinates defined by the
+ array.
+ cube(ARRAY[1,2]) == '(1,2)'
+
+ cube(float8[], float8[]) returns cube
+ This makes a cube, with upper right and lower left coordinates as
+ defined by the 2 float arrays. Arrays must be of the same length.
+ cube('{1,2}'::float[], '{3,4}'::float[]) == '(1,2),(3,4)'
+
cube(cube, float8) returns cube
This builds a new cube by adding a dimension on to an existing cube with
the same values for both parts of the new coordinate. This is useful for
***************
*** 267,272 ****
--- 277,289 ----
cube_ur_coord returns the nth coordinate value for the upper right corner
of a cube. This is useful for doing coordinate transformations.
+ cube_subset(cube, int[]) returns cube
+ Builds a new cube from an existing cube, using a list of dimension indexes
+ from an array. Can be used to find both the ll and ur coordinate of single
+ dimenion, e.g.: cube_subset(cube('(1,3,5),(6,7,8)'), ARRAY[2]) = '(3),(7)'
+ Or can be used to drop dimensions, or reorder them as desired, e.g.:
+ cube_subset(cube('(1,3,5),(6,7,8)'), ARRAY[3,2,1,1]) = '(5, 3, 1, 1),(8, 7,
6, 6)'
+
cube_is_point(cube) returns bool
cube_is_point returns true if a cube is also a point. This is true when the
two defining corners are the same.

These include changing the precision from single precision to double
precision and adding some new functions.
+
+ ------------------------------------------------------------------------
+
+ Additional updates were made by Joshua Reich <[EMAIL PROTECTED]> in July 2006.
+
+ These include cube(float8[], float8[]) and cleaning up the code to use
+ the V1 call protocol instead of the deprecated V0 form.
