ROTATEZ

#define ROTATEZ	(		angle,
			vx,
			vy,
			vz
	)

Value:

        tmp1 = vx*cos(angle) - vy*sin(angle);\
        tmp2 = vx*sin(angle) + vy*cos(angle);\
        vx = tmp1;\
        vy = tmp2

ROTATEY

#define ROTATEY	(		angle,
			vx,
			vy,
			vz
	)

Value:

        tmp1 = vx*cos(angle) + vz*sin(angle);\
        tmp2 = - vx*sin(angle) + vz*cos(angle);\
        vx = tmp1;\
        vz = tmp2

#define ROT_HP_HC	(		hp,
			hc,
			omega
	)

Value:

    if ((omega) != 0.0) { \
        REAL8 _c = cos(2.0 * omega); \

            (hp)->data->data[_ind] = _c * _x + _s * _y; \
            (hc)->data->data[_ind] = _c * _y - _s * _x; \
        } \
    } else ((void)0)
