| Yorick Function ReferenceIndex Range FunctionsRange functions are executed from left to right if more than one appears
in a single index list. The following range functions reduce the rank of
the result, like a scalar index:
 min   minimum of values along index 
max   maximum of values along index
 sum   sum of values along index
 avg   average of values along index
 rms   root mean square of values along index
 ptp   peak-to-peak of values along index
 mnx   index at which minimum occurs
 mxx   index at which maximum occurs
 The following functions do not change the rank of the result, like an
index range. However, the length of the index is changed as indicated by
+1, -1, or 0 (no change):
 cum, psum   +1, 0, partial sums of values along index 
dif         -1, pairwise differences of adjacent values
 zcen        -1, pairwise averages of adjacent values
 pcen        +1, pairwise averages of adjacent interior values
 uncp        -1, inverse of pcen (point center) operation
 For example, given a two-dimensional array x, x(min,max)
returns the largest of the smallest elements along the first dimension.
To get the smallest of the largest elements along the second dimension,
use x(,max)(min).
