oop - Finding an object with a certain property value in an array of objects in MatLab? -

i have class follows

class car      properties         index         price         color     end end 

i created array of these objects , added several cars array. cars have unique index. want find car in array index 5. how can this?

you can 1 of 2 ways:

1. create array indices , compare against 5 yield logical array can use index array grab ones meet criteria.

   item = obj_array([obj_array.index] == 5) 

2. use findobj locate object in array particular property/value pair (note works if using handle class , not value class)

   item = findobj(obj_array, 'index', 5)
