Suppose I have an ordered string structure like this: {'word1','word2','word3','word4','word5','word6'.etc.}
And I have another one, which is a subset, for example {'word5','word2','word4'}.
And I want to extract indices corresponding to the first structure, so the result should be the ordered vector [5,2,4];
Which is the shortest solution for this, whithout a for cycle?

Ran in:
big_list = {'word1','word2','word3','word4','word5','word6'};
small_list = {'word5','word2','word4'};
[~,idx] = ismember(small_list,big_list)
idx = 1×3
5 2 4
