Prerequisite

• Array

Etymology

This file contains global functions which perform element by element logical operations on arrays.

Synopsis

These functions perform element by element logical operations on arrays. The two arrays must conform, except for allEQ which returns false if the arrays do not conform.

There are two classes of functions. One class returns a LogicalArray. In these functions, the value of an element of the LogicalArray is the value of the logical operation applied to the corresponding elements of the input Arrays. 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 arrays for the "all" functions (e.g. allLE()), and returns true if the logical operation returns true for any elements of the input arrays for the "any" functions (e.g. anyLE()).

For instance allLE (a, b) implies 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]).

Caution: 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 < b;

This example sets the elements of l (a<b). The result of the comparison is a LogicalArray.

Example

 Vector<int> a(10);
 Vector<int> b(10);
 bool result;
...
 result = allLT (a, b);

This example sets result to true if, for all elements, a<b.

Motivation

One wants to be able to perform logical operations on arrays.

To Do

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

template<class T >

bool casacore::ArrayLogical_global_functions_Array_logical_operations::allLE	(	const Array< 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.

The operator forms of array logical operations which return a single bool have been replaced by these "all" functions. The operator forms of array logical operations now return a LogicalArray.

The arrays must conform except for allEQ, which will return false if the arrays have different shapes.

LogicalArray casacore::ArrayLogical_global_functions_Array_logical_operations::operator<=	(	const Array< T > &	l,
		const Array< T > &	r
	)

Element by element comparisons between the "l" and "r" arrays.

The result is a LogicalArray. The arrays must conform or an exception is thrown.

The Vector, Matrix and Cube version are present to bypass the problems due to the existence of automatic comparison inline templates in standard algorithm library, producing a single bool value.

template<class T >

LogicalArray casacore::ArrayLogical_global_functions_Array_logical_operations::operator<=	(	const Array< T > &	array,
		const T &	val
	)

Element by element comparisons between an array and a scalar, which

behaves as if it were a conformant array filled with the value "val." The result is a LogicalArray.

Thrown Exceptions

• ArrayConformanceError

Array<size_t> casacore::ArrayLogical_global_functions_Array_logical_operations::partialNTrue	(	const Array< T > &	array,
		const IPosition &	collapseAxes
	)

The same functions as above, but determine ntrue and nfalse for the given axes only.

The result is an array with a shape formed by the remaining axes. For example, for an array with shape [3,4,5], collapsing axis 0 results in an array with shape [4,5] containing ntrue or nfalse for each X line. Summing for axes 0 and 2 results in an array with shape [4] containing ntrue or nfalse for each XZ plane.
