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

javascript - How to get MySQL query result returned using $.ajax -

I'm trying to update is a JavaScript, when you hover over an image, a devi Floats near your mouse, this information is stored in an .js file as an array, for example. text [0] = ["image 1", "data1"] text [1] = ["image2", "data2"] In the past, if the array change / add / delete the data it will need to upload a new copy .js file, if the data was attached / deleted, then the new image needs a change in .dwt file Which can update each file using the .dwt file as the main template, which can result in 20+ pages They are uploaded I thought that I can automate this record by using the database and using the database if they are active and use only mysql queries which are active, such a black app The database can be added and disabled, thus eliminating the need for every soft upload of the file. To do this, I had planned to store the information in the database and create the above array based on the results, by researching how to us...
