match

Position of a value in a vector.

Syntax

v = match(lookup_value, lookup_array, match_type)

Description

Returns the position (1-based) of lookup_value in lookup_array.

• match_type = 1 (default) — largest entry ≤ lookup_value (array must be ascending)
• match_type = 0 — exact match
• match_type = -1 — smallest entry ≥ lookup_value (array must be descending)

Example

match('c', {'a','b','c','d'}, 0)    % 3
