Name:arraylib::Reform - Reform the dimensions of a hyperrectengular array
Synopsis:
[array] [dim1 dim2 ... dimn] Reform -> [reformedArray]
Description:
"Reform" changes the dimensionality i.e. the nesting of an array. The
result is a hyperrectangular array of the given dimensions. The order
of elements is not changed.
"Reform" relates to "Dimensions" in the following way:
Given a hyperrectangular array [a] of "Dimensions" [d], these
statements are true:
a d Reform -> a
a Flatten d Reform -> a
a dv Reform d Reform -> a, for any valid dimension vector [dv]
Diagnostics:
If the new dimensionality is not consistent with the numer of elements
in the array, /RangeCheck is raised.
Remarks:
The new dimensionality must not change the number of elements in the
whole array, that is, dim1*...*dimn must equal the number of the
flattened source array.
Availability:
"Namespace"-dictionary "arraylib".
References:
This routine is inspired by IDL's REFORM() routine.
