一个超级简单的程序，但是总报错，请高手给看一下~

do循环的参数能不是正整数么
我没用do循环，用的for循环。出错提示
Error using HW4>sigemay (line 29)
Not enough input arguments.
Error in HW4>YTraction (line 59)
ty=-tau(d)*cos(d)-sigemay*sin(d);
Error in HW4 (line 6)
v=(-u0(d)*cos(d)-XTraction(d)*du(d)-YTraction(d)*dv(d))*0.01*(6.28/360); ty=-tau(d)*cos(d)-sigemay*sin(d);应更改为
ty=-tau(d)*cos(d)-sigemay(d)*sin(d); hongtianwenduo 发表于 2013-4-13 20:58 static/image/common/back.gif
ty=-tau(d)*cos(d)-sigemay*sin(d);应更改为
ty=-tau(d)*cos(d)-sigemay(d)*sin(d);
啊啊啊，捂脸
