Macro Definition Documentation

◆ CExp

#define CExp (   v)
Value:
{ \
double e = exp(v.x);\
v.x = e*cos(v.y); \
v.y = e*sin(v.y); \
}

Definition at line 256 of file pprz_geodetic_double.c.

◆ CI

#define CI (   v)
Value:
{ \
double tmp = v.x; \
v.x = -v.y; \
v.y = tmp; \
}

Definition at line 250 of file pprz_geodetic_double.c.

◆ CSin

#define CSin (   v)
Value:
{ \
CI(v); \
struct DoubleVect2 vstar = {-v.x, -v.y}; \
CExp(v); \
CExp(vstar); \
VECT2_SUB(v, vstar);\
VECT2_SMUL(v, v, -0.5); \
CI(v); \
}
