Here are the regular expressions that match your description. I'm using regexpi() which is not case sensitive. If you want case sensitivity, use regexp() instead with the same inputs. The expresssions are wrapped in isempty() and negated so each line will return a 1 if the expression is satisfied and a 0 if it is not satisfied.
The first one 'endsWithHiphenWordNum' returns TRUE if the input ends with [hyphen, word, number] with any amount of space between each. If you'd like to limit it to only 1 space between each, you can replace the "\s+" with a single space " " (without the quotes). The second one 'endsWithWordNumNum' returns TRUE if the input ends with [word, number, number] with any amount of space between each. Lastly, both expressions end with "$" which means that the input string is considered a match only if the expression is at the very end of the string.
a = 'example 1 is - car 6';
b = 'example 2 car 5 32';
endsWithHiphenWordNum = ~isempty(regexpi(a, '-\s+[a-z]+\s+\d+$')) % - aaa 11
endsWithWordNumNum = ~isempty(regexpi(b, '[a-z]+\s+\d+\s+\d+$')) % aaa 11 11
if endsWithHiphenWordNum
% do this
elseif endsWithWordNumNum
% do this
end
