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...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
