How to compare a cell to a single value?

I want to create a mask where it is true if value in cell == frame. This works

mask=(behaviours.frame(:) == frame);

print(behaviours.frame(:))
   585
   586
   586
   587
   587
   588
   588
   589
   589
   590
   590
   591
   591
   592
   592
   593
   593
   594
   594

but this does not. How do I make it work? thx

mask=(behaviours_currframe.ID{:} == ID);
>> behaviours_currframe.ID{:}

ans =

    'pedestrian1'


ans =

    'pedestrian2'

mask = strcmp({behaviours_currframe.ID}, ID)
