MATRIX DIMENSIONS MUST AGREE error while input strings/char

for i = 1:x

for j = 1:y

if (A{i} ~= B{j})

temp{idx} = B{j};

i = (idx + 1);

end

end

end

A{i} is an array filled with chars

B{j} is also an array filed with chars

When running the program, it won't compare at if (A{i} ~= B{j}) and gives the MATRIX DIMENSIONS MUST AGREE error.

How can I fix this?

Use ~strcmp(A{i},B{j}) instead of A{i} ~= B{j}
