छवि दर्ज करें यहाँ वर्णन मैंने उपरोक्त छवि के वेग फ़ील्ड रेखा की छानबीन करने के लिए कोड लिखा था, लेकिन किसी नतीजे के परिणामस्वरूप अंधेरे का कुल जाल हो गया है क्या कोई मुझे मदद कर सकता है? यहाँ मेरा कोड है। 

  x = linspace (-45, -15,1500) y = लिनसेपेस (-3,9,600) थर (एक्स, वाई, वीएक्स, वीजे)

वीएक्स और वीजे एचडीएफ 5 डेटा से हैं और उनके आकार हैं (600 एल, 1500 एल)। या, क्या वेक्टर क्षेत्र को छानने का एक तरीका है जब -25 से -30 से एक्स और -5 से -1 के लिए z

अंधेरे की छवि इस प्रकार है:

मैंने तब कोड की कोशिश की 

  x, y = numpy। मैशग्रीड (numpy.linspace (-45, -15,1500), numpy.linspace (-3,9,600)) तरकश (एक्स [:: 20, :: 20], y [:: 20, :: 20], वीएक्स [:: 20, :: 20], वीजे [:: 20, :: 20], रंग = 'आर', कोण = 'एक्सआई', पैमाने_अनुमति = 'एक्सआई', पैमाने = 9000000)

और छवि इस तरह दिखती है यहां छवि विवरण दर्ज करें

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...
