plexplexplex类型的定义

typedef struct {plex _Val;plex;

plexplex”关键字来声明。例如

plex c1, c2;

plex类型的变量c1和c2。

plexplex类型运算

1. 加法c1 + c2

2. 减法c1 – c2

3. 乘法c1 c2

4. 除法c1 / c2

5. 模长cabs(c1)

6. 幅角carg(c1)

j(c1)

8. 实部creal(c1)

ag(c1)

plex类型的示例

cludecludeplex.h>

tain()

{plex c1 = 1.0 + 2.0 I;plex c2 = 3.0 – 4.0 I;

tfag(c1));tfag(c2));

plex c3 = c1 + c2;tfag(c3));

plex c4 = c1 c2;tfag(c4));

= cabs(c1);tf);

gle = carg(c1);tfgle);

plexjj(c1);tfjjagj_c1));

输出结果为

c1 = 1.000000 + 2.000000i

c2 = 3.000000 – 4.000000i

c1 + c2 = 4.000000 – 2.000000i

c1 c2 = 11.000000 + 2.000000i

c1| = 2.236068

arg(c1) = 1.107149j(c1) = 1.000000 – 2.000000i

plexplex类型。
