C++ (Cpp) sumw Examples

Example #1

File: WeightedMvnModel.cpp Project: MarkEdmondson1234/Boom

  SpdMatrix WMS::center_sumsq(const Vector &mu)const{
    SpdMatrix ans = sumsq();  // sum wyy^T
    ans.add_outer(mu, sumw()); // wyyT + w.mu.muT

    ans -=  as_symmetric(mu.outer(sum_, 2));
    return ans;
  }

Example #2

File: 10924.c Project: mythnc/online-judge-solved-lists

int main(void)
{
    char str[MAXCHAR];

    while (scanf("%s", str) == 1) {
        if (prime(sumw(str)))
            printf("It is a prime word.\n");
        else
            printf("It is not a prime word.\n");
    }
    return 0;
}

Example #3

File: WeightedMvnModel.cpp Project: MarkEdmondson1234/Boom

 SpdMatrix WMS::var_hat()const{
   if(sumw()==0) return sumsq()*0.0;
   return center_sumsq()/sumw();
 }

Example #4

 Vector WMS::ybar()const{
   if( sumw()==0) return sum().zero();
   return sum()/sumw();}
