How to convert categorical array contains 'yes' or 'no' to logical array?

Hi, I have a table consist of categorical array which is just contains 'yes' and 'no', ex:

a = [yes yes no no yes no]

I want to convert it to a logical array translating yes to 1 and no to 0. ex:

b = [1 1 0 0 1 0]

Could you show me the way to do it? Thanks!

What is the type of your variable "a"? a = [yes yes no] is not valid Matlab code. Please post some code, which creates your input data. This is better than a rough description by words.

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

a = {'yes' 'yes' 'no' 'no' 'yes' 'no'} ;

b = strcmp(a,'yes')
