Macro Definition Documentation

c_add

#define c_add	(		c,
			a,
			b
	)

Value:

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

Complex Addition c = a + b.

c_eq

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

Complex equality testing.

c_sub

#define c_sub	(		c,
			a,
			b
	)

Value:

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

Complex Subtraction c = a - b.

cc_conj

#define cc_conj	(		a,
			b
	)

Value:

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

cc_mult

#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; \
    }

Complex-Complex Multiplication.

cs_mult

#define cs_mult	(		c,
			a,
			b
	)

Value:

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

Complex-Double Multiplication.
