Implementing np.subtract.outer for index of array([[array .... structure in python -

-

मेरे पास सूचकांक का निम्न सेट है; 

  ind = array ([[array ( [[1, 2, 3, 6]), [सरणी ([2, 3, 7] [0, 1, 4]), [सरणी ([0, 1, 2, 5]), ), [सरणी ([2, 5, 6, 7, 10]), [सरणी ([0, 4, 5, 8])], [सरणी ([1, 4, 5, 6, 9])], [सरणी ([2, 5, 6, 7, 10]) ], [सरणी ([5, 8, 9, 10, 13]), [सरणी ([3, 6, 7, 11])], [सरणी ([4, 8, 9, 12])], [ सरणी ([6, 9, 10, 11, 14])], [सरणी ([7, 10, 11, 15]), [सरणी ([8, 12, 13])], [सरणी ([9, 12, 13, 14]), [सरणी ([10, 13, 14, 15]), [सरणी ([11, 14, 15])]])   
  X , जो नीचे दिखाया गया है  
  एक्स = सरणी ([[0., 0.], [0.33333333, 0.], [0.66666667, 0.], [0, 0, 03333333], [0.33333333, 0.33333333], [0.66666667, 0.33333333], [1.33333333], [0., 0.66666667], [0.33333333, 0.66666667], [0.66666667, 0.66666667], [1., 0.66666667], [0., 1], [0.33333333, 1.], [0.66666667, 1.], [1., 1.]])   < P>  forloop  टी का उपयोग किए बिना एक कारगर तरीका है ओ निम्नलिखित मैट्रिक्स प्राप्त करें;  
  ए = [एक्स [0,0] -एक्स [0,0] एक्स [0,0] -एक्स [1,0] एक्स [0,0] -एक्स [4, 0] एक्स [1,0] -एक्स [0,0] एक्स [1,0] -एक्स [1,0] एक्स [1,0] -एक्स [2,0] एक्स [1,0] -एक्स [ 5,0] एक्स [2,0] -एक्स [1,0] एक्स [2,0] -एक्स [2,0] एक्स [2,0] -एक्स [3,0] एक्स [2,0] - एक्स [6,0] ... ... ... एक्स [15,0] -एक्स [11,0] एक्स [15,0] -एक्स [14,0] एक्स [15,0] -एक्स [ 15,0]]   
 मैंने पहले ही np.subtract.outer और np.subtract की कोशिश की है।  इंडस्ट्रीज़  संरचना के साथ काम करना बहुत मुश्किल है (बस का उपयोग करके  X [ind, 0]  कहते हैं)। मैं  इंडस्ट्रीज़  संरचना को बदलना पसंद नहीं करता मैट्रिक्स  ए  को प्राप्त करने के लिए  forloop  का उपयोग किए बिना क्लीवर मार्ग की तलाश कर रहा है।  
   
 
 
 यदि आप इंडेक्स की सरणी को बदलते हैं जैसे:  
 / P> 
  ind = ind.flatten ()   
 आप जो चाहते हैं वह प्राप्त कर सकते हैं:  
  a = X [: , 0] ans = [एनपी.ओन्स (लेन (आई)) * एक [0] -ए [i] I के लिए में]   
  इंडस्ट्रीज़ की अपनी मूल परिभाषा के साथ  आपको इसके बजाय  i [0]  का उपयोग करना चाहिए।  
 
 संपादित करें: इसमें सुधार किया जा सकता है (जैसा कि @जैम द्वारा सुझाया गया है):  < पूर्व>  ans = [एक [0] - एक [i] के लिए I में]

I do not know how to use mysqli_result like in the past. Is this OK? How is right WHERE status = 'popup' and creditsp> = 1 and (CH) from $ res = mysqli_query ($ con, "SELECT` id`,` usrid`, `url` site Lt; cf || cf = 0) sequence by rand () border 1 "); $ Urll = mysqli_result ($ res, 0, "url"); $ Ownerid = mysqli_result ($ res, 0, "Elixir"); $ Citid = mascile_salt ($ res, 0, "id"); Use fetch_assoc on the results: $ line = $ res-> gt; Fetch_assoc (); $ Urll = $ line ['url']; $ Owner = $ line ['nectar']; $ Site id = $ line ['id']; If there are more than one line, then: while ($ line = $ res-> fetch_assoc ()) {// process $ Line}

Delphi: missing interface declarations for UI Automation methods -

-
Such a basic question is, but I'm stuck ... I get I'm trying to start with UI Automation using Delphi 2007 (Win32) on Windows 7. It seems that I do not have to use some methods and types. I have the .NET Framework 4.x installed on this machine, but I have imported a type of library from the C: \ Program Files (x86) \ reference assembly \ Microsoft \ Framework \ v3.0 \ UIAutomationClient.dll ... ... I am looking for UIAutomationClient_TLB: UIAutomationClientMajorVersion = 1; UIAutomationClientMinorVersion = 0; I'm not sure that this is the problem (wrong version). I can declare the following with no problem: var UIAuto: IUIAutomation; Element: IUIAutomationElement; But the methods of IUIAutomationElement are missing. For example, there is nothing in the interface declaring this method: IUIAutomationElement.TryGetCurrentPattern () ... which msdn.microsoft According to .com, there is an interface method which is returning to at least NET 3.0. Where do...
