WebA Matrix and a vector can be multiplied only if the number of columns of the matrix and the the dimension of the vector have the same size. \(Ax=c\hspace{30px}\normalsize … WebIn Mathematica the dot operator is overloaded, and can be matrix multiplication, matrix-vector multiplication,vector-matrix multiplication, or the scalar dot product of vectors, depending on context. If possible, Mathematica also conforms the vectors as needed. For example, a nxm matrix can multiply a m-wide row vector without objection. Reply Flag Web6 iun. 2016 · 2x2 matrix multiplied by a 2x1 column vector gives erratic results. For example: A= [3,-2;2,-2] times v= [1;-1] works, but fails if A= [1,2;3,4]. The problem seems to be that in Matlab matrix multiplication the elements in row A are multiplied by the corresponding columns in B. Here B has only one column, and needs that the column … pioneer work and learn michigan
