%% Multiply Two Vectors %% % Create a 1-by-4 row vector, |A|, and a 4-by-1 column vector, |B|. A = [1 1 0 0]; B = [1; 2; 3; 4]; %% % Multiply |A| times |B|. C = A*B %% % The result is a 1-by-1 scalar, also called the _dot product_ or _inner % product_ of the vectors |A| and |B|. Alternatively, you can calculate % the dot product $A \cdot B$ with the syntax |dot(A,B)|. %% % Multiply |B| times |A|. C = B*A %% % The result is a 4-by-4 matrix, also called the _outer product_ of the % vectors |A| and |B|. The outer product of two vectors, $A \otimes % B$, returns a matrix.
