I have a two column item 1st, Column is child's name and 2nd column is his/her choice of toys. For a given list of Toys I bought, make a table against each toy to each child.

A=["Child1" "Dog"

"Child1" "Cat"

"Child1" "Babbie"

"Child2" "Tractor"

"Child2" "Plane"

"Child2" "Bus"

"Child2" "Car"

"Child3" "Helicoptor"

"Child3" "Crane"

"Child3" "Tiger" ];

n=length(A);

Unrecognized function or variable 'A'.

m=length(M);
%AA= [Toy Name; Which Child does the Toy belong?]
AA=zeros(n,1);
%
for i=1:n
    for j=1:m
        if A(i,1)== M(j,2)
        AA(i,1)= M(j,1);
        end
    end
end
AA;

%A= Child Toys

A=["Child1" "Dog"

"Child1" "Cat"

"Child1" "Babbie"

"Child2" "Tractor"

"Child2" "Plane"

"Child2" "Bus"

"Child2" "Car"

"Child3" "Helicoptor"

"Child3" "Crane"

"Child3" "Tiger" ];

%AA=[Toys Child ]<---Need the answer as below; I'm new to String arrays use of for/if loops

AA=[ "Babbie" "Child1"

"Bus" "Child2"

"Dog" "Child1"

"Helicoptor" "Child3"

"Tiger" "Child3" ];

child = A(:,1) ;
toy = A(:,2) ;
T = table(child,toy)

T = 10×2 table

My answer should be the below, because only a few of the total list of toys were bought.

AA=[ "Babbie" "Child1"

"Bus" "Child2"

"Dog" "Child1"

"Helicoptor" "Child3"

"Tiger" "Child3" ];
