As stated in the documentation you can use the == operator to select elements in a categorical array that are in a particular category.

>> A = categorical({'yes','yes','no','no','yes','no'}) 
A = 
  1×6 categorical array
     yes      yes      no      no      yes      no 

>> A == 'yes'
ans =
  1×6 logical array
   1   1   0   0   1   0
