MATLAB: Store values from loop in an array

Question

I want to compare each individual element of A with each element of B and store the logical answer in a table. Thanks for the help!

A= categorical ({'A','B','C'});

B= categirial({'B','D'});

TableA = zeros(3,2);

for i = length(A)

for j=1:length(B)

if isequal (A(i),B(j))

Answer=1;

tableA (i,j) = [Answer];

else

Answer=0;

tableA (i,j)= [Answer];

end

end

end

Answer 1

Typos in your code:

for i=1:length(A)

And change tableA to TableA (MATLAB is case sensitive).

Or, you could get rid of the loops entirely:

    TableA = (A'==B);

On older versions of MATLAB:

    TableA = bsxfun(@eq,A',B);
