The combination of multiplication of two numbers followed by summing of products hints at matrix multiplication, so let’s see if we can set up the calculation as a vector multiplication problem, making it considerably easier to accomplish with Matlab.

32 Notice that MATLAB does not distinguish between a 1x1 matrix (which is what vTw really is) and its single entry. Neither do we ordinarily, but we should remember that the product of a scalar with a matrix is not in general an instance of matrix multiplication. Notice also that the dot product is symmetric as regards v and w.

Matrix multiplication is denoted by A*B, but MATLAB also has many uses for A .*B which denotes “freshmen” (or elementwise) multiplication of matrices of the same size. After all, thinking of matrices as representing functions (collections of function values), this kind of multiplication simply corresponds to the (pointwise) product of two ...
Matrix multiplication - MATLAB mtimes
Multiplication of pure imaginary numbers by non-finite numbers might not match MATLAB. The code generator does not specialize multiplication by pure imaginary numbers—it does not eliminate calculations with the zero real part. For example, (Inf + 1i)*1i = (Inf*0 – 1*1) + (Inf*1 + 1*0)i = NaN + Infi.

Matrix Multiplication. Matrix multiplication is quite a bit more involved. We give the definition first. Suppose is a matrix and is a matrix, then . is a matrix with. for and . Note that in this product, the number of columns of the matrix A must be the same as the number of rows of the matrix B. Here is an example. Assume that. and

The same is true of matrix addition and subtraction, but – and this has important ramifications for your work with Matlab – matrix multiplication is generally not commutative: that is, if A and B are two matrices, in general . The significance of this is that the ordering of matrices is important when you’re setting up the calculation of ...
