MATLAB: Vectorization of ismember function

Question

Hello, I am interested in using the ismember function for strings by row with out using a for loop. For example I would have

 A = {'cat','dog','bird'}

as my input vector and

B = {'cat','dog';'dog','bird'}

using ismember in a for loop

 for k = 1:2
 M(k,:) = ismember(A,b{k,:});
 end

would return the matrix;

 M = [1 1 0 ; 0 1 1].

Right now I have this written in a for loop but I was wondering if there is a way to do it without one. Thank you in advance.

Answer 1

M = cell2mat(arrayfun(@(ii)ismember(A,B(ii,:)),(1:size(B,1))','un',0));

or

[~,b] = ismember(B,A);
M = accumarray([repmat((1:size(b,1))',size(b,2),1),b(:)],1);
