matlab - Error in MuPAD command: An arithmetical expression is expected. [exp] -

-

मैं द्वारा दिए अभिव्यक्ति लिखना चाहता था:

इस में calculate_dk और calculate_T फ़ंक्शन हैं इनपुट तर्क ii और jj । मैं theeta चर के संबंध में इस समीकरण को अधिकतम करना चाहता था लेकिन, इस उद्देश्य के लिए मैं आवश्यक अभिव्यक्ति के रूप में असमर्थ हूं मैं symsum फ़ंक्शन 

  sys ii jj f = symsum (symsum (nchoosek (15, ii-1) * nchoosek (15, jj-1) * ऍप (थीटा * गणना _ डीके (ii-1, jj-1) + सिग्मा * गणना की गणना (ii-1, jj-1)), जे जे, 1, 16), ii, 1,16);

लेकिन इसकी त्रुटि दे रही है

म्यूपैड के उपयोग में त्रुटि म्यूपैड कमांड में त्रुटि: एक अंकगणितीय अभिव्यक्ति की उम्मीद है [एक्सपा] sym / privateUnaryOp में त्रुटि (पंक्ति 845)
सीएसएम = मपाडमेक्स (सेशन, एल्ग्स {1}।, Varargin {:});

सिम / एक्सपी में त्रुटि (पंक्ति 6 )
वाई = निजी यूनिवर्सिओप (एक्स, 'सिम्बोज् :: मैप', 'एक्सपी');

एनाका _मॉडेल_फंक्ट में त्रुटि (रेखा 24)
एफ = सिम्स्यूम (सिम्सम (एनोकोसेक (15 , Ii-1) * नॉकोसेक (15, जे जे -1) * एपीपी (थीटा * गणना / डीके (ii-1, jj-1) + सिग्मा * गणना की गई टीटी (ii-1, jj-1)), जे जे, 1, 16) , Ii, 1,16);

कृपया एक समीकरण बनाने में मेरी मदद करें ताकि मैं इसे अनुकूलित कर सकूं (अधिकतम के संबंध में अधिकतम)।

I am working on a page that will create a team. I just want to create a selection box which will list all the users of all the users. After that, the user can select more than one friend (i.e. 5) and can send the request to these 5 people to join the team but I am having problems I did this: Select $ sql = "Select i. *, Join * Connect with M * m.id = i.clique_id where adder_id =: id"; $ Stmt = $ db- & gt; Query ($ sql, array ('id' = & gt; $ _SESSION ['id'])); While ($ record = $ stmt-> fetch ()) {$ surname = $ record ['surname']; } and this: & lt; Select multiple = "true" name = "category" well id = "category" name = "category" category = "" & gt; & Lt; Option value = "& lt ;? php echo $ surname ;? & gt;" & Gt; & Lt ;?

There are two panels in my JInternalframe. I want to add TopPanel to Jtree to nominate another. But I can not add Jaitari to the top of the panel. Please help me in this piece of code: DefaultMutableTreeNode root = new DefaultMutableTreeNode ("deck"); DefaultMutableTreeNode Item Clubs = New DefaultMutableTreeNode ("Club"); AddAllCard (itemClubs); Root.add (itemClubs); DefaultMutableTreeNode item = New DefaultMutableTreeNode ("Diamonds"); AddAllCard (itemDiamonds); Root.add (itemDiamonds); DefaultMutableTreeNode Itemspads = New DefaultMutableTreeNode ("Spades"); AddAllCard (itemSpades); Root.add (itemSpades); DefaultMutableTreeNode item increases = new DefaultMutableTreeNode ("heart"); AddAllCard (itemHearts); Root.add (itemHearts); Default Trimodel Tree Model = New DefaultTreeModel (Route); Tree = new jetty (tree modal); ScrollPane = new JScrollPane (tree); // scrollPane.setViewportView (tree); .

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
