MATLAB: How to associate specific values to specific verbiage

findMATLAB

I've got 2 arrays: A = [1; 2; 3; 1; 2; 3]; and B = [ ];

I need array B to contain [Lost; Found; Unk; Lost; Found; Unk] based on the values found in A.

I'm using the find function to locate the indices of the values 1, 2, and 3. But I'm not sure what to do next.

Any ideas are appreciated. Thanks.

A =  [1; 2; 3; 1; 2; 3]
v={'Lost'; 'Found'; 'Unk'}
B=v(A)

a1=find(A==2)-1; %find the index of the 2
a2=find(A==3)-1; %find the index of the 3
a2=repmat(a2,2,1) %duplicate the 3 indexes
B=sort([a1;a2])'; %join and sort the solution, also transpose
%I transposed B because of your B example
