/// Multiply a scalar and a double precision 3-dimensional vector.
///
/// # Brief I/O
///
/// ```text
/// VARIABLE I/O DESCRIPTION
/// -------- --- --------------------------------------------------
/// S I Scalar to multiply a vector.
/// V1 I Vector to be multiplied.
/// VOUT O Product vector, S * V1.
/// ```
///
/// # Detailed Input
///
/// ```text
/// S is a double precision scalar used to multiply the vector
/// V1.
///
/// V1 is a double precision 3-dimensional vector, which is to
/// be scaled by S.

///
/// # Detailed Output
///
/// ```text
/// VOUT is a double precision 3-dimensional vector containing
/// the product of the scalar with the vector V1.
/// ```
///
/// # Exceptions
///
/// ```text
/// Error free.
/// ```
///
/// # Particulars
///
/// ```text
/// For each value of the index I from 1 to 3, this subroutine
/// performs the following multiplication
///
/// VOUT(I) = S * V1(I)
///
/// No error checking is performed to guard against numeric overflow
/// or underflow.
/// ```
///
/// # Examples
///
/// ```text
/// The numerical results shown for this example may differ across
/// platforms. The results depend on the SPICE kernels used as
/// input, the compiler and supporting libraries, and the machine
/// specific arithmetic implementation.
///
/// 1) Define a sets of scalar double precision values and use them
