Tests whether two keys are equal for dictionary purposes.

Category: Language Fundamentals > Data Types

Syntax

tf = keyMatch(k1, k2)

Returns true if k1 and k2 are the same key.

Description

keyMatch is the equality test of a dictionary lookup. It is stricter than isequal in the sense that the two keys must be of the same kind, and text is compared case-sensitively. Together with keyHash it defines when two keys count as one entry.

Input arguments

k1, k2: Two key values.

Output arguments

tf: Logical scalar.

Example

Comparing keys

keyMatch('ab', 'ab')
keyMatch('ab', 'AB')
keyMatch(1, 1)

Output

ans = logical
   1
ans = logical
   0
ans = logical
   1
