这几天我可惨透了,硬着头皮去读一种TBasic编的程序(新浪上都不能搜索到这个词),各位
请看看以下的源码什么意思?尤其是其中的Ravg和Iavg的用法,作为实参传递,但
又不是回调函数,TBasic中A[]表示的数组,同时我也未见哪里有定义:(
....
10000 CALL Zop(Ex,Rx,Ey,Ry,Ex,Ry,Ey,Rx,Denr,Deni,Ravg,Iavg)
....
21530 Zop: ! ------------------------------------------------------
21540 SUB Zop(Arr,Acc,Brr,Bcc,Crr,Ccc,Drr,Dcc,R_out,I_out,Ravg,Iavg)
21550 OPTION BASE 1
21560 DECLARE LOCAL R1,R2,I1,I2
21570 R1 = Ravg[Arr,Acc]*Ravg[Brr,Bcc]-Iavg[Arr,Acc]*Iavg[Brr,Bcc]
21580 R2 = Ravg[Crr,Ccc]*Ravg[Drr,Dcc]-Iavg[Crr,Ccc]*Iavg[Drr,Dcc]
21590 I1 = Ravg[Arr,Acc]*Iavg[Brr,Bcc]+Iavg[Arr,Acc]*Ravg[Brr,Bcc]
21600 I2 = Ravg[Crr,Ccc]*Iavg[Drr,Dcc]+Iavg[Crr,Ccc]*Ravg[Drr,Dcc]
21610 R_out = R1-R2
21620 I_out = I1-I2
21630 END SUB
