Introduction

Multiplication of vector with a scalar value in the Matlab program:

Let us suppose a vector, V = [x1,x2,x3,x4] Then we want to multiply the vector, V with a scalar value, n then the Matlab statement becomes V*n
In the case of the multiplication of a vector, V with a first element, V(1) of the same vector is as V*V(1)
V*V(1) will results in a new vector with a multiplication of each value in the V vector with a V(1) element.
