WebThe linear combination concept leads naturally to the definition for matrix - vector multiplication. One multiplies a matrix A to a column vector x simply by taking the linear combination of the columns of A, using the entries of the vector x for the scalars in the linear combination. It is important to note that this definition requires that ... WebMultiply Two Vectors Copy Command 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 C = 3 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 ⋅ B with the syntax dot (A,B).
