WebThe matrix-vector product inputs a matrix and a vector and outputs a vector. If you think of a matrix as a set of row vectors, then the matrix-vector product takes each row and dots it with the vector (thus the width of the matrix needs to equal the height of the vector). In general: Ax = b(A is an mxn matrix, x is an Rn vector, and b is Rm vector) WebUsually with matrices you want to get 1s along the diagonal, so the usual method is to make the upper left most entry 1 by dividing that row by whatever that upper left entry is.
