Prerequisite

Etymology

MaskArrLogi is short for MaskedArrayLogical, which is too long by AIPS++ file naming conventions. This file contains global functions which perform element by element logical operations on masked arrays.

Synopsis

These functions perform element by element logical operations on masked arrays. With two arrays, they must both conform, and the result is done element by element, for those locations where the mask of the MaskedArray is True. For two MaskedArrays, the "and" of the masks is used.

There are two classes of functions. One class returns a MaskedLogicalArray. In these functions, the value of an element of the MaskedLogicalArray is the value of the logical operation applied to the corresponding elements of the input MaskedArrays. The other class of functions returns a single Bool. The return value is True if the logical operation returns True for all elements of the input masked arrays for the "all" functions (e.g. allLE()), and returns True if the logical operation returns True for any elements of the input masked arrays for the "any" functions (e.g. anyLE()). The functions which return a single Bool throw an exception if the AND of the masks of the input masked arrays has no True elements.

For instance allLE (a, b) imples that every element of a is less than or equal to every element of b. Note that with this definition allLE (a, b) and allGE (a, b) can both be false (e.g. a = [1,0] b = [0,1]).

NB comparison between two zero-sized arrays is not defined (should it throw an exception?).

Example

   Vector<Int> a(10);
   Vector<Int> b(10);
   LogicalVector l(10);
      . . .
   l = a(a>0) < b(b>0);

This example sets those elements of l where ((a>0) && (b>0)) to (a0) && (b>0)) are unchanged. The result of the comparison is a MaskedLogicalArray. The assignment from this MaskedLogicalArray to the LogicalArray l only assigns those elements where the mask is True.

Example

   Vector<Int> a(10);
   Vector<Int> b(10);
   Bool result;
      . . .
   result = allLT (a(a>0), b(b>0));

This example sets result to True if, for all elements where ((a>0) && (b>0)), a

Motivation

One wants to be able to mask arrays and perform logical operations on those masked arrays. Since the masked arrays are only defined where the masks are True, the result must be a MaskedLogicalArray, or a single Bool.

To Do

Reconsider where the origin of the returned LogicalArray should be located.

Member Description

Bool allAND (const MaskedArray<T> &l, const Array<T> &r)
Bool allOR (const MaskedArray<T> &l, const Array<T> &r)

Element by element comparisons between the "l" and "r" arrays. The result is true only if the comparison is true for every element of the arrays for which the mask of the MaskedArray is True. For two MaskedArrays, the "and" of the masks is used.
