Multiplication of a vector by a number

The block implements the multiplication of each of the elements of the vector value at the first input with the scalar value at the second input:

where a_i(t) is the i-th element of the input vector signal a(t) at the first input, b(t) is the signal at the second input, scalar one; y_i(t) is the element of the output vector signal y(t). The dimension of the output is equal to the dimension of the first input.
