The linear combination concept leads naturally to the definition for matrix - vector multiplication. multpl_col1(col1) = '+' + '+' matpl_col2(col1,col2) . To solve the problem, we would need three vectors, one for each of the three columns of the matrix. If A and B are not scalars, then A*B is only defined if the number of columns in A . If the sizes of A and B are compatible, Lets suppose that we have a linear equation for the scalar and scalars scalarity. The first row is the first row vector of the matrix A. 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 AB with the syntax dot(A,B).
