哪位高手帮我修改一下下面这段程序的错误，我看了实在是改不出．急用．．．先谢谢了！


double bucmul(double ar,double ai,double br,double bi,int m,int n,int k,double cr,double ci)

{
int i,j,l,u,v,w;
double p,q,s;
for(i=0;i<=m-1;i++)
for(j=0;j<=k-1;j++)
{u=i*k+j;
cr[u]=0.0; error (C:\Documents and Settings\基地12号\桌面\Text1.c(85) : error C2109: subscript requires array or pointer type

ci[u]=0.0;

q=ai[v]*bi[w];

}
}
return(cr,ci);
}
