मेरे पास 5x5 मैट्रिक्स है 

  ए = [0 0 0 0 1; 0.36 0 0 0 1; 0 0.25 0 0 1; 0.35 0 0 0 1; 0 0 0.28 0 1];   
 मैं विकर्ण तत्वों पर विचार किए बिना मैट्रिक्स के निचले त्रिकोणीय तत्वों को निकालना चाहता हूं। इसलिए, परिणामस्वरूप मैट्रिक्स होनी चाहिए   सी = [0.36 0 0.35 0 0.25 0 0 0 0.28 0]   
 मुझे ये बताएं कि मैं यह कैसे प्राप्त कर सकता हूं।   
 
 
 मैं यह मान रहा हूँ कि मैट्रैक्स के प्रारूप के आधार पर यह मैटलैब है।  < P> यदि आप एक सदिश वेक्टर में निचले त्रिकोणीय हिस्से के तत्व चाहते हैं, तो आप इसे एक पाश के साथ कर सकते हैं (हालांकि मुझे यकीन है कि किसी के पास निफ्टी वेक्टरयुक्त दृष्टिकोण होगा):  
  C = []; N = 1 के लिए: आकार (ए, 1) सी = [सी, ए (एन + 1: एंड, एन) ']; आउट   
 आउटपुट है:  
  सी = 0.36 0.00 0.35 0.00 0.25 0.00 0.00 0.00 0.28 0.00   
 यदि इसके बजाय आप पूर्ण 5x5 मैट्रिक्स चाहते हैं, तो आप इसका दूसरा तर्क का प्रयोग करेंगे:  
  सी = त्रिल (ए, -1);   
 आउटपुट है:  
  सी = 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.28 0.00 0.00

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

c# - How to check if a certain method/class/API exists in Xamarin iOS? -

-
After the it is recommended to check for a specific API like this IsiOS7 bool public stable {Returns UIDevice.CurrentDevice.CheckSystemVersion (7, 0); }} If (Util.IsiOS7) {// call iOS 7 API} and {// iOS 6.1 or earlier API call} The same should go for iOS 8. Now I have read that you should check whether there is a certain method or class exists rather than checking the version. Here comes the RespondsToSelector that should be something like this if (RespondsToSelector (new selector ("edgesForExtendedLayout"))) EdgesForExtendedLayout = UIRectEdge.None. But how will one examine if a whole class exists like UIAlertController ? In Objective-C, there is no NSClassFromString I have seen in some such purpose - if ([UIAlertController class]) {// ...} Will such a move happen? type type = type Gettype ("UIAlertController"); If (type! = Null) {// iOS 8 API} other {// iOS 7 or lower} How will this happen in C #? Or to check for UIAlertController...
