keyHash

Create a hash code for a dictionary key.

Syntax

  • H = keyHash(A)

Input argument

  • A - array

Output argument

  • H - scalar: uint64, Hash code.

Description

H = keyHash(A) returns a uint64 scalar representing the input array, A.

The keyHash function computes a hash code derived from the characteristics of the input.

For custom classes, keyHash might require overloading to guarantee proper equivalence.

Example

keyHash({'a', 'b', 1})
keyHash({1, 'a', 'b'})
