Octave: Check if cell array of strings contains string

If you have a cell array of strings in Octave like this:

arr = {"a", "bc", "def"}

you can check if it contains a specific string like "a" using

contains_a = any(strcmp(arr, 'a'))

Example:

arr = {"a", "bc", "def"}

contains_a = any(strcmp(arr, 'a'))
contains_x = any(strcmp(arr, 'x'))

disp(contains_a) # 1
disp(contains_x) # 0
