Numpy linear solver in Python -

-

I was using numpy.linalg.solve to solve a set of linear equations, coefficients matrix a < / P> 

  a = [[1.00000000e + 00 0.00000000e + 00 0.00000000e + 00 ..., 0.00000000e + 00 0.00000000e + 00 0.00000000e + 00] [0.00000000e + 00 1.00000000e + 00 0.00000000e + 00 ..., 0.00000000e + 00 0.00000000e + 00] [0.00000000e + 00 0.00000000e + 00 1.00000000e + 00 ..., 0.00000000e + 00 0.00000000e + 00 0.00000000e + 00] .. ., [0.00000000e + 00 0.00000000e + 00 0.00000000e + 00 ..., 1.1920680 9A + 12 -1.22559480 A + 12 3.460 9 2750e + 11] [0.00000000e + 00 0.00000000e + 00 0.00000000e + 00 .. ., -1.80896480e + 14 2.54068164e + 12 -8.65658340e + 12] [0.00000000e + 00 0.00000000e + 00 0.00000000e + 00 ..., 6.92185500e + 11 4.23578160e + 12 -6.79632634e + 12]] < / Code>

and B matrix 

  [0.0, 0.0, 0.0, 0.0 .................... ...... 150000]

and I think it should be the output of matrix such as 0.0, 0.0]

However, the actual result is non-zero value, someone help me Can the reason?

Thank you in advance.

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...
