in code have 3 functions nested. 1 calls 1 calls another. code execution slow. led believe because these api calls can contain lot of data , getting ran more once having impact on performance. code sample follows: $data['object'] = 'domain'; $data['action'] = 'read'; $data['format'] = 'json'; if($response = $this->request($data)){ $obj = json_decode($response,true); ....... } }else{ return $response; } so basically, obj gets data. can create private array in form , write results , run statements against instead of calling api several times? i led believe because these api calls can contain lot of data , getting ran more once having impact on performance. the golden rule of optimization do not optimize without measuring first . use profiler run code , tell code getting executed , taking longest time. if don't measure, speedi...

i trying vectorize weighted sum couldn't figure out how it. have created simple minimal working example below. guess solution involves either bsxfun or reshape , kronecker products still have not managed working. rng(1); n = 200; t1 = 5; t2 = 7; = rand(n,t1,t2); w1 = rand(t1,1); w2 = rand(t2,1); b = zeros(n,1); = 1:n j1=1:t1 j2=1:t2 b(i) = b(i) + w1(j1) * w2(j2) * a(i,j1,j2); end end end = b; you use combination of bsxfun , reshape , permute accomplish this. we first use permute move n dimension 3rd dimension of a . multiply w1 , transpose of w2 create grid of weights. can use bsxfun perform element-wise multiplication ( @times ) between grid , each "slice" of a . can reshape 3d result m x n , sum across first dimension. b = sum(reshape(bsxfun(@times, w1 * w2.', permute(a, [2 3 1])), [], n)).'; update there's simpler approach use matrix multiplication perform summation you. unfortunately has broken % create grid of weigh...
