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) WebMar 21, 2014 · a = 3x + 4y + 5z - 12 b = 2x + 8y + z - 11 c = 9x + 7y -z - 15 where The left hand variables don't appear on the right side and vice versa. On the left side, there is only one variable. Then, x, y and z can take values of any combination and are called free variables.
