int sqrt_vector
(
	Vector **target_vpp,
	const Vector *vp
);

DESCRIPTION

This routine calculates the element-wise square root of a vector with the KJB library creation semantics. If we are respecting missing values, then the sqrt() of a missing value (DBL_MISSING) is DBL_MISSING.

RETURNS

NO_ERROR on success, and ERROR on failure, with an error message being set. This routine will fail if any of the element of the input vector is negative.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
