i have csv file following data structure: p1_1,p2_1,p3_1 p1_2,p2_2,p3_2 p1_3,p2_3,p3_3 and want plot p2 againt p3 in matlab, wrote code: function plotdata dbstop if error filename='c:\\temp\\out100-2.csv'; m=csvread(filename); plot(m(2),m(3)); but plot empty. checked , m has data, way using plot not right. how can fix problem can plot it? m(2) , m(3) 2 scalar values, hence plot single point. you need supply vectors plot , e.g.: plot(m(:,1),m(:,2)) this plots data first , second columns of csv file.

it's question title says, have included hook in module: def self.included(base) puts 'included' base.extend api end my api requires variables on object exists none of them being created. i've tried: base.variable_name = [] %x|#{base}.variable_name = []| base.instance_variable_set(:@variable_name,[]) base.instance_exec{@variable_name = []} 1-2 inside of base.instance_exec using self instead of base yet none of them work, console complains variable_name= doesn't exist. what.the.hell? how variable exist on base object inside of included hook? in end, had use @variable_name ||= [] inside of function definitions work, don't works. if want know why don't it's because defining object attributes in once places means can find they're defined , change initial value, whereas here have track down change (not hard it's principle). personal preference guess.

one can define eventhandler in constructor: uibarbuttonitem logoutbutton = new uibarbuttonitem (uibarbuttonsystemitem.stop, logoutbuttoneventhandler); private void logoutbuttoneventhandler(object sender, eventargs args){ console.writeline("logout"); } is possible remove eventhandler afterwards? perhaps not using eventhandler @ , instead use action / target properties of uibarbuttonitem ? don't find examples. anonymous methods used time. how do that? instantiate object , set handler: var logoutbutton = new uibarbuttonitem (uibarbuttonsystemitem.stop) logoutbutton.clicked += logoutbuttoneventhandler; to remove afterwards use -= syntax: logoutbutton.clicked -= logoutbuttoneventhandler; just beware of commom pitfalls when because may cause memory leaks.

what purpose of r temporary file created in every directory workspace saved? data contain , safe delete? that file holding file save.image() while r waits file argument succeed. help(save.image) , safe argument - safe - logical. if true, temporary file used creating saved workspace. temporary file renamed file if save succeeds. preserves existing workspace file if save fails, @ cost of using disk space during save. so file contains entire workspace image , best leave there in case r fails save workspace normally. i'm guessing if see file, r has failed rename file may want search file , check contents before deleting temporary file.

i wondering of both methods faster: selecting container , form @ in 1 statement: jquery $('#submitform form') or using jquery's .find() selector: jquery $('#submitform').find('form') the .find() approach faster because first selection handled without going through sizzle selector engine – id-only selections handled using document.getelementbyid( ), extremely fast because native browser. so jquery $('#submitform').find('form') is faster than jquery $('#submitform form') selector optimization less important used be, more browsers implement document.queryselectorall() , burden of selection shifts jquery browser.

a site work saw doubling of it's direct traffic recorded in google analytics. there doesn't seem obvious external reason increase (like promotion or something) i'm looking possible technical reason. when loading homepage , monitoring real time traffic sources, see 2 hits in rapid succession each time reload page. however i'm using ga debugger extension in chrome , it's showing 2 expected function calls: ga('create') , ga('send', 'pageview'). the site has other event tracking set each event wrapped in event listener in js aren't firing automatically. , if should show in ga debugger anyway so i'm @ loss. can't think of why happening, let alone direct traffic opposed other sources. have ideas? thanks!

i creating hash in ruby , want write json file, in correct format. here code: temphash = { "key_a" => "val_a", "key_b" => "val_b" } fjson = file.open("public/temp.json","w") fjson.write(temphash) fjson.close and here contents of resulting file: key_aval_akey_bval_b i'm using sinatra (don't know version) , ruby v 1.8.7. how can write file in correct json format? require json library, , use to_json . require 'json' temphash = { "key_a" => "val_a", "key_b" => "val_b" } file.open("public/temp.json","w") |f| f.write(temphash.to_json) end your temp.json file looks like: {"key_a":"val_a","key_b":"val_b"}

similar this question , i'm looking way load templates via javascript promises. issue i'm running returning compiled template backbone view. note: this.getfile() returns new promise , fetches template expected. template: function(attributes) { this.getfile('/path/to/template').then(function(tpl) { var compiled = handlebars.compile(tpl); return compiled(attributes); }, function(error) { console.error('failed!', error); }); } within view's initialize , have listener set to initialize: function() { this.model.on('change', this.render, this); } which triggers expected when data fetched server. the problem when render function executes line render: function() { ... this.$el.html(this.template(attributes)); ... } nothing renders html expect. i'm sure i'm missing simple within template promise callback, no matter change, html not render , no errors appear. like @muistooshort have pointed out. tem...
