function [posns] = strmatch_multi(keys, strs)
% STRMATCH_MULTI Find where each key occurs in list of strings.
% [pos] = strmatch_multi(key, strs) where key is a string and strs is a cell array of strings
% works like the built-in command sequence pos = strmatch(key, strs, 'exact'),
% except that pos is the first occurrence of key in strs; if there is no occurence, pos is 0.

% [posns] = strmatch_multi(keys, strs), where keys is a cell array of strings, 
% matches each element of keys. It loops over whichever is shorter, keys or strs.
