i stuck @ vectorizing tricky loop in matlab/octave: [nr, nc] = size(r); p = rand(nr, k); q = rand(k, nc); = 1:nr j = 1:nc if r(i,j) > 0 eij = r(i,j) - p(i,:)*q(:,j); k = 1:k p(i,k) = p(i,k) + alpha * (2 * eij * q(k,j) - beta * p(i,k)); q(k,j) = q(k,j) + alpha * (2 * eij * p(i,k) - beta * q(k,j)); end end end end the code tries factorize r p , q, , approaching nearest p , q update rule. example, let r = [3 4 0 1 1; 0 1 0 4 4; 5 4 3 1 0; 0 0 5 4 3; 5 3 0 2 1], k=2, alpha=0.01 , beta=0.015. in real case, use huge sparse matrix r (that's why need vectorization), , k remain small (less 10). goal of whole script producing prediction value every 0 elements in r, based on non 0 elements. got code here , written in python. this looks 1 of cases not code can vectorized. still, can make bit better now. [nr, nc] = size(r); p = rand(nr, k); q = rand(k, nc); = 1:nr j = 1:nc if r(i,j) > 0 ...

is there way avoid graph:: repetition in implementation file, yet still split class header + implementation? such in: header file: #ifndef graph_h #define graph_h class graph { public: graph(int n); void printgraph(); void addedge(); void removeedge(); }; #endif implementation file: graph::graph(int n){} void graph::printgraph(){} void graph::addedge(){} void graph::removeedge(){} i'm guessing avoid lots of "unnecessary typing". sadly there's no way rid of scope (as many other answers have told you) class defined function prototypes in nice rows, copy/paste implementation file ctrl-c classname:: on clip board , run line ctrl-v.
