anonymous

问题 I am trying to create two anonymous functions and plot them using a single fplot statement. The following code works to plot a single function: f = @(x) sin(x) fplot(f, [-3, 3]) However, when I include the following, it doesn't work: g = @(x) cos(x) fplot([f, g], [-3, 3]) Does anyone know what is the issue here? 回答1: If you really must do this: >> f = @sin; >> g = @cos; >> hold on >> cellfun(@(func) fplot(func, [-3, 3]), {f, g}) This applies the function handle @(func) fplot(func, [-3, 3]) to

问题 I am trying to achieve anonymous personalization in a ASP.net environment. I know that ASP.NET 2.0 provide Profile. However, I want to avoid traffic to the database as much as possible since the site I am working on is a relatively high traffic site. The other obvious solution is cookie, but given the limitation of cookie, I was wondering if anyone have any efficient method to store information into cookie. Does anyone know how amazon or yahoo deals anon. personalization? Ultimately, We are

问题 Edit ok, great feedback here, got me pointed in the right direction. Use case for invoking anonymous closure is in Scalatra routing layer. I have a bunch of routes that are grouped together under various types, in this example, requests common to teams: class Router { type TeamType <: _Controller with _Team get("""(schedules|rosters|teamresults|teamstats)/\d{8}""".r) { val clazz :: date = captures val obj = (clazz match { case "schedules" => new RosterController case "rosters" => new

问题 I have created an immediate object in OCaml. let x = object (self) val dataMember = 3 method aMethod = print_endline "Called a method" end;; As the object doesn't have a name (is it considered anonymous?), how can it be correctly represented in UML? Thanks. 回答1: You could give it a nonce-name, or some other formulaic value. "Correctly" in this context really just means something that will be clear. There is no "right answer" handed down from the International UML Standards Body or anything.

问题 In this question I saw an anonymous type expression with an unfamiliar syntax: new { MyObjectID = g.Key, totalSum } At first I thought it ( , totalSum } ) was a syntax error as no key is specified, but it compiles and works in C#3.0. I have verified this syntax in LINQPad (2.x -> C#3): var y = ":-)"; var q = new { Y = y, y, y.Length, }; q.Dump(); Result: (anon type) { Y = ":-)", y = ":-)", Length = 3 } Where in the specification is this syntax defined? (Answers should include an applicable

问题 This question already has answers here : How do I return the response from an asynchronous call? (36 answers) Closed 6 years ago . Consider: function ajaxCall(url, callback) { $.ajax({ type: "GET", url: url, success: function (data) { // <-- fail point: where does the returned data go, now? // do stuff with data if ( callback ) { var ret = callback(); if ( ret !== undefined ) { return ret; } } } }); } function fooBar() { return ajaxCall('some/url', function () { // do stuff return some_value;

问题 I am trying to understand exactly how to setup a bucket that is generally private but allows anonymous uploads with restrictions. The specific criteria are: The bucket is mostly private and requires my key/secret to add/remove/update/list files. There is a "directory" (i.e. key prefix) called "incoming" that will allow anonymous users to upload content to but not list. The bucket has a one day expiration on all content. As a bonus I would like the "incoming" directory to have a 30 minute

问题 When should anonymous methods be used when defining a delegate and when should formally defined methods be used when defining a delegate ? 回答1: If you need to use the same logic in more than one place, it makes sense to use a separate method. If you only need to use the logic once and it's fairly short, it makes sense to use an anonymous function. If the delegate needs access to local variables in the method which is creating it, anonymous functions act as closures which can also be very

问题 I am a beginning javascript programmer. I am trying to create something similar to Lightbox 2, but much simpler. The only reason why I want to do it from scratch on my own is so that I can learn. However, I've been stuck on the last critical part where it displays the image. I believe the problem lies where I try to use onclick with assignment to an anonymous function: elem[i].onclick = function (){liteBoxFocus(imgSource,imgTitle); return false;}; . If you run my code and try clicking on the

问题 What is the best way to implement a "memory" or persistence for an anonymous vote? The other day I was browsing some site (unfortunately I forgot the URL), and I could quickly "thumbs up" or "thumbs down" an item. So I voted on several items. I then closed all my browser instances, deleted all the browser history and files. I went back to the site to vote on some of the same items but it "knew" that I had already voted. So I am wondering what's the best way to accomplish this I have read
