[julia-users] of the products of vectors faster ?

[paul analyst]

Is it possible to calculate the sum of the products of vectors faster? 
without the loop?

(k,l)=size(Z);
(m,n)=size(czerw_rot);
F=zeros(k,m);println("stworzyl pusta F");
tic();
for j=1:m, i=1:k;
    F[i,j]=sum(czerw_rot[j;:].*Z[i;:]);
end;

Z is very big  ..
