Based on this definition, we can see that the scalar multiplication by 1 preserves any matrix, and the scalar multiplication by 0 changes any matrix into a zero matrix. WebA vector times a scalar. Multiplying a vector by a scalar produces another vector of the same size in which each element of the original vector has been multiplied by the scalar. Calculate w = -2u, where u is defined above. The vector u has 3 elements 1, 2, 3 from before, so the vector w has elements -2, -4, -6. >> w = -2 * u. key west fantasy festival 2011 uncensored
