int multiply_vector_by_scalar
(
	Vector **target_vpp,
	const Vector *source_vp,
	double scalar
);

DESCRIPTION

This routine multiplies the vector in "source_vp" by the scalar in "scalar", and puts the result in the vector pointed to by "target_vpp". That vector is created or resized as necessary. If we are respecting missing values, then the sqrt() of a missing value (DBL_MISSING) is DBL_MISSING. More specifically, the first argument is the adress of the target vector. If the target vector itself is null, then a vector of the appropriate size is created. If the target vector is the wrong size, it is resized. Finally, if it is the right size, then the storage is recycled, as is.

RETURNS

NO_ERROR on success, and ERROR on failure with the error message being set. Currently, failure can only be due to storage allocation error.
