WebWe can multiply a vector by a scalar (called "scaling" a vector): Example: multiply the vector m = (7,3) by the scalar 3 a = 3 m = (3×7,3×3) = (21,9) It still points in the same direction, but is 3 times longer (And now you know why numbers are called "scalars", because they "scale" the vector up or down.) Polar or Cartesian A vector can be in: WebC = A.*B multiplies arrays A and B by multiplying corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each element of the other array. Web23 feb. 2024 · multiplying row vector by a scalar .
