Function Documentation

zsl_phy_mass_center()

int zsl_phy_mass_center	(	struct zsl_vec *	m,
		struct zsl_vec *	x,
		struct zsl_vec *	y,
		struct zsl_vec *	z,
		zsl_real_t *	mx,
		zsl_real_t *	my,
		zsl_real_t *	mz
	)

Calculates the three coordinate position of the center of mass of a set of objects given their masses and positions.

Parameters

m	Vector that contains the mass of each object in kilograms.
x	Vector that contains the x coordinate of each object in meters.
y	Vector that contains the y coordinate of each object in meters.
z	Vector that contains the z coordinate of each object in meters.
mx	Pointer to the x position of the center of mass in meters.
my	Pointer to the y position of the center of mass in meters.
mz	Pointer to the z position of the center of mass in meters.

Returns

0 if everything executed properly, -EINVAL if any of the masses has a negative value or the total mass is zero.
