matlab - How to calculate the values of non-explicit function for all points of a meshgrid? -


मान लें कि मेरे पास फ़ंक्शन है 

  f = @ (x, y) g ( X, y)

g स्पष्ट नहीं है x और y मूल्यों को इनपुट करने के बाद इसे संख्यात्मक रूप से गणना की जानी चाहिए।

कैसे मैं अंकों के इस फ़ंक्शन के सभी मानों की गणना और सहेज सकता हूं

<पूर्व> [x, y] = मेशग्रीड (0: 0.1: 1,0: पी / 10: 2 * पीआई);

मैं f [x, y] को कॉल करता हूं, लेकिन यह काम नहीं करता।

आपके पास ऐसा करने के दो तरीके हैं आपका फ़ंक्शन जी को मैट्रिक्स के साथ काम करना चाहिए, या आपको मूल्य एक एक करके देना चाहिए 

  फ़ंक्शन eval_on_mesh () f1 = @ (x, y) g1 (x, y); F2 = @ (एक्स, वाई) जी 2 (एक्स, वाई); [X, y] = मेशग्रीड (0: 0.1: 1,0: पीआई / 10: 2 * पीआई); % # यदि आपका फ़ंक्शन मैट्रिक्स के साथ काम करता है, तो आप इसे यहां आंकड़े, सर्फ (एफ 1 (एक्स, वाई)) की तरह कर सकते हैं; % # यदि आपका फ़ंक्शन नहीं है, तो आपको मूल्य एक एक = sol = zeros (आकार (x)) देना चाहिए; I = 1 के लिए: आकार (एक्स, 1) जम्मू = 1 के लिए: आकार (एक्स, 2) सोल (i, j) = f2 (x (i, j), y (i, j)); अंत अंत आंकड़ा, सर्फ (सोल); अंत समारोह res = g1 (x, y) res = x ^ 2 + y ^ 2; अंत समारोह res = g2 (x, y) res = x ^ 2 + y ^ 2; अंत

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket? SupportForm supportForm: form [supportTicket] = form (mapping ("question" -> text, "priority" -> text) (apply support ticket. (HelpText.update) What are the good practices here? What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....
