Giving default values to only some function variables in Matlab -


मैंने एक Matlab फ़ंक्शन बनाया 

  फ़ंक्शन फू (argone, argtwo)   
 समारोह की शुरुआत उन वेरिएबल्स के लिए डिफ़ॉल्ट विकल्प की अनुमति देती है अगर फ़ंक्शन को केवल एक या शून्य तर्क के साथ ही कहा जाता है  
  function foo (argone, argtwo) अगर (~ मौजूद ('argone', 'var')) argone = defaultargone; अंत अगर (~ मौजूद ('आर्ट्स', 'var')) argtwo = defaultargtwo; अंत ...% कोड के बाकी   
 हम फ़ंक्शन को  
  foo ()% के रूप में कॉल कर सकते हैं डिफ़ॉल्ट मान argone और argtwo foo को असाइन किए जाते हैं Myargone)% डिफ़ॉल्ट मान दिया गया है argtwo foo (myargone, myargtwo)% कोई डिफ़ॉल्ट मानों का उपयोग नहीं किया जाता है   
 लेकिन कैसे आर्गोन के लिए डिफ़ॉल्ट मान देने में सक्षम हो?  
 यदि फ़ंक्शन को  
  foo (~, myargtwo)   
 के साथ कहा जाता है, तो कोई भी डिफ़ॉल्ट मान नहीं है; एल्गोन को शून्य मान मिलता है (यह मूलभूत मूल्य नहीं है)  
 आपकी मदद के लिए धन्यवाद   
 
 
 एक वैकल्पिक तरीका खाली इनपुट को संभालने का विकल्प शामिल करना होगा:  
  फ़ंक्शन फ़ू (argone, argtwo) अगर ~ मौजूद है ('argone', 'var') || आइसमेटी (argone) argone = डिफॉल्टगोन; अंत अगर ~ मौजूद है ('आर्गटू', 'var') || इस्पामी (आर्गटू) argtwo = defaultargtwo; अंत में   
 फिर इनमें से किसी भी काम करना चाहिए:  
  foo () foo ([], []) foo (argone) foo ([], argtwo )

c - Performance of System() -

After the function in C, for the system (), it affects the hardware counters, so how do you order that The example displayed for the example you are trying to view lets the IM use the display API (PAPI) and the program is a precompiled matrix multiplication application. PAPI_start_counters (); System ("./matmul"); PAPI_read_counters (); // Print the values ​​PAPI_stop_counters (); I'm clearly missing a bit, but I'm trying to figure out what it is possible to say, counter receiving a program im running Is through use. With my tests I will get wild numbers like below, they are clearly wrong, just want to find out why total bicycle =========== 140733358872510 instructions complete =========== 4203968 Floating Point Instructions =========== Floating Point Operations =========== 4,196,867 Weight ======= ==== 140733358872804 store ======= ==== 4204037 branches taken =========== 15774436 System () Normally it is a very slow function, on Linux, it is ...

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
