Nominal basis.

basis() [3/6]

Heed::basis::basis	(	const vec &	p,
		const std::string &	fname )

Longitudinal basis. z-axis is parallel to p. y-axis is vector product of z_new and z_old x-axis is vector product of y_new and z_new If p is parallel to z_old, the copy of old basis is created. If p is anti-parallel to z_old, the inverted copy of old basis is created.

basis() [4/6]

Heed::basis::basis	(	const vec &	p,
		const vec &	c,
		const std::string &	pname )

More sophisticated basis. ez is parallel to p, ez=unit_vec(p) ey is perpendicular to plane which have p and c, ey=unit_vec(ez||c) ex is vector product of y and z, ex=ey||ez If p is parallel to c, or p is anti-parallel to c, vecerror=1 if(length(p)==0||length(c)==0)) vecerror=1;
