Define Documentation

#define c_add	(	c,
		a,
		b		)

Value:

{ (c)->r = (a)->r + (b)->r; \
                         (c)->i = (a)->i + (b)->i; }

Definition at line 31 of file scomplex.h.

#define c_eq	(	a,
		b		)	( (a)->r == (b)->r && (a)->i == (b)->i )

Definition at line 52 of file scomplex.h.

#define c_sub	(	c,
		a,
		b		)

Value:

{ (c)->r = (a)->r - (b)->r; \
                         (c)->i = (a)->i - (b)->i; }

Definition at line 35 of file scomplex.h.

#define cc_mult	(	c,
		a,
		b		)

Value:

{ \
        float cr, ci; \
        cr = (a)->r * (b)->r - (a)->i * (b)->i; \
        ci = (a)->i * (b)->r + (a)->r * (b)->i; \
        (c)->r = cr; \
        (c)->i = ci; \
    }

Definition at line 43 of file scomplex.h.

#define cs_mult	(	c,
		a,
		b		)

Value:

{ (c)->r = (a)->r * (b); \
                           (c)->i = (a)->i * (b); }
