i have applied this solution averaging every n rows of matrix. although solution works in general had problems when applied 7x1 array. have noticed problem when using -= operator. make small example: import numpy np = np.array([1,2,3]) b = np.copy(a) a[1:] -= a[:-1] b[1:] = b[1:] - b[:-1] print print b which outputs: [1 1 2] [1 1 1] so, in case of array a -= b produces different result a = - b . thought until these 2 ways same. difference? how come method mentioning summing every n rows in matrix working e.g. 7x4 matrix not 7x1 array? note: using in-place operations on numpy arrays share memory in no longer problem in version 1.13.0 onward (see details here ). 2 operation produce same result. answer applies earlier versions of numpy. mutating arrays while they're being used in computations can lead unexpected results! in example in question, subtraction -= modifies second element of a , uses modified second element in operation on third element...

i have been able query data mysql database , put array variable $results, not able put part of array, password or regtime in $results varible separate variables. doing wrong? this select function in databse class querying data database using perameter of $query. works posts page, dont think problem. // select function public function select($query){ $result = $this->connection->query($query); while ( $obj = $result->fetch_object()){ $results[] = $obj; } return $results; } this login function in query class putting submitted username query , passing select function above pull results username, returned login function , stored in $results variable. checks whether variable empty , if kills script, working get: 1) yay!!!! 2)and displayed print_r() is: array ( [0] => stdclass object ( [id] => 1 [username] => dillon [fname] =...
