Multiply a matrix by a vector matlab
Web7 mar. 2013 · Accepted Answer: James Tursa. Given a vector V, I can define an element-wise multiplication on another vector W as V.*W. I'd like to be able to likewise multiply the rows or columns of a matrix by a vector V in the same sense. In other words, given a vector with components V (i) and a matrix with components M (i,j), I'd like to output a … Web16 nov. 2009 · I highly recommend you use the MMX toolbox of matlab.

WebBy the definition, number of columns in A equals the number of rows in y . First, multiply Row 1 of the matrix by Column 1 of the vector. Next, multiply Row 2 of the matrix by Column 1 of the vector. Finally multiply Row 3 of the matrix by Column 1 of the vector. WebTo define multiplication between a matrix and a vector (i.e., the matrix-vector product), we need to view the vector as a column matrix . We define the matrix-vector product only for …
