i'm trying implement observer av player in pure swift. i'm getting error: message received not handled. because object argument in constructor of observer i'm using nil? i've placed example code below. thanks player.addobserver(self, forkeypath: "status", options:nskeyvalueobservingoptions(), context: nil) player.addobserver(self, forkeypath: "playbackbufferempty", options:nskeyvalueobservingoptions(), context: nil) player.addobserver(self, forkeypath: "playbacklikelytokeepup", options:nskeyvalueobservingoptions(), context: nil) player.addobserver(self, forkeypath: "loadedtimeranges", options: nskeyvalueobservingoptions(), context: nil) private func deallocobservers(player: avplayer) { player.removeobserver(self, forkeypath: "status") player.removeobserver(self, forkeypath: "playbackbufferempty") player.removeobserver(self, forkeypath: "playbacklikelytokeepup"...

what doing wrong here (matlab)? i want obtain lines ones below: syms b d m l expr11 = -m-b*l*(b-m-d); jqdfe11 = simplify(expr11); with following loop: for k=1:8 lhs=['jqdfe1',num2str(k)]; rhs=['expr1',num2str(k)]; eval('lhs = simplify(rhs)'); end but getting error: error using eval: undefined function 'simplify' input arguments of type 'char' if want working. both lhs , rhs strings whereas in code, interpreted variables. want: eval([lhs ' = simplify(' rhs ')']); lhs , rhs names variables stored strings, , want use actual strings when building string eval . btw, don't know why doing you're doing, consider not using eval . it's bad practice. see post loren shure mathworks on why shouldn't use it: http://blogs.mathworks.com/loren/2005/12/28/evading-eval/

i developing webservice data intensive. unfortunately of data returned not needed calls, might needed call. an overly simplified response might below: response : { a, b, c, d : { x : { } y, z } } i want provide flexibility callers such can request specific data big object. thought of achieving exposing enums, , taking list of enum input. each enum map field in response. example if caller needs , d, can specify passing list of enums immutablelist.of(get_enum_a, get_enum_d) , @ web service end can compute , d. questions: there better way of taking input (other enum) of data needed caller? i give control user on more fine grained data, eg. can specify part of d needed. get_enum_d_x. at server end, thinking of implementing using command pattern, having command each enum , executing if corresponding enum present in list. here d facade. if granular data requested don't use facade instead use command x. issue c...

i have large vector contains monotonically increasing data or duplicate, looking this: data = [0 1.1 2.2 3.3 4.4 4.4 4.4 4.4 5.5 6.6 6.6 6.6 7.7]; in data set, i'm interested in duplicate entries (in case, 4.4 , 6.6 ). have sorta clunky solution extract these values, feel matlab should have one-liner solution extract result like result = [4.4 6.6]; the combination of unique , diff enough, find not necessary. out = unique(data(~diff(data)))

i have program creates array: list1 = zeros((x, y), dtype=complex_) currently using x = 500 , y = 1000000 . initialize first column of list formula. subsequent columns calculate own values based on preceding column. after list filled, display multidimensional array using imshow() . the size of each value (item) in list 24 bytes. sample value code is: 4.63829355451e-32 when run code y = 10000000 , takes ram , system stops run. how solve problem? there way save ram while still being able process list using imshow() easily? also, how large list can imshow() display? there's no way solve problem (in general way). computers ( as commonly understood ) have limited amount of ram, , require elements in ram in order operate on them. an complex128 array size of 10000000x500 require around 74gib store. you'll need somehow reduce amount of data you're processing if hope use regular computer (as opposed supercomputer ). a common technique partitioning ...

what difference in python between doing: a, b = c, max(a, b) and a = c b = max(a, b) what having 2 variable assignments set on same line do? your 2 snippets different things: try a , b , c equal 7 , 8 , 9 respectively. the first snippet sets 3 variables 9 , 8 , 9 . in other words, max(a, b) calculated before a assigned value of c . essentially, a, b = c, max(a, b) push 2 values onto stack; variables a , b assigned these values when popped off. on other hand, running second snippet sets 3 variables 9 . because a set point value of c before function call max(a, b) made.
