Macro Definition Documentation

#define equal	(		A,
			B,
			I
	)		(fabs((A)->x[I] - (B)->x[I]) < Eps)

Parameters

A	First point
B	Second point
i	coordinate to compare

Returns

True if the i coordinates are almost equal

Definition at line 75 of file point.h.

#define objective	(		Z,
			A,
			O
	)		HV(Z, A)

Parameters

Z	The zero bounding point
A	The point to analyze
O	The one bounding point

Returns

The objective value to maximize, must be > 0

Definition at line 84 of file point.h.

Function Documentation

void parsePoint	(	char *	S,
		point *	p,
		double	max
	)

Reads a point from the '\0' terminated string.

Parameters

S	The string containing the coordinates, separated by spaces or ' '
p	The position where to store the point

Definition at line 57 of file point.c.
