小编Sur*_*Rao的帖子

读Numpy快速教程,我无法理解这句话.

a = np.arange(12).reshape(3,4)
b1 = np.array([False,True,True]) 
b2 = np.array([True,False,True,False])
>>> a[b1,b2]  
array([ 4, 10])

为什么a[b1,b2]是array([4,10])不是array([[4,6],[8,10]])？

我有以下数组作为输入以降序排序值:

var cars = ["8587009748118224023Po","8587009748118224023PP","8587009748118224023P,","8587009748118224023P$","8587009748118224023P<","8587009748118224023P?"]

在C#中,我正在使用OrderByDescending并获得以下输出

C#代码:

var rslt= cars.OrderByDescending(a => a);

结果:

8587009748118224023PP,8587009748118224023Po,8587009748118224023P<,8587009748118224023P?,8587009748118224023P,,8587009748118224023P$

在Javascript中,我使用排序和反向并获得以下不同的结果

javascript代码:

cars.sort();
cars.reverse();

结果:

8587009748118224023Po,8587009748118224023PP,8587009748118224023P?,8587009748118224023P<,8587009748118224023P,,8587009748118224023P$

任何人都可以帮我如何在C#中对值进行排序,就像javascript一样？

npm start我在使用角度页面时收到以下错误。

API 调用需要什么

我需要通过 Jenkins 指标插件的 API 调用获得每个构建的时间线信息。我正在使用 Web API 来获取我的 jenkins 中的工作数据。然而，打电话$JenkinsUrl/metrics/APIkey却无济于事。知道如何获取这些信息吗？

运行命令“ionic cordova build android --prod”后出现以下错误。

在Julia中,我想将定义为2D数组的Vector的数据转换为Matrix的2D数组.如下例所示,我想将数据转换为数据t,但到目前为止我还没有成功.我该如何处理此案？

julia> s = [[1 2 3], [4 5 6], [7 8 9]]
3-element Array{Array{Int64,2},1}:
 [1 2 3]
 [4 5 6]

julia> t = [[1 2 3]; [4 5 6]; [7 8 9]]
3××3 Array{Int64,2}:
 1  2  3
 4  5  6
 7  8  9

julia> s |> typeof
Array{Array{Int64,2},1}

julia> t |> typeof
Array{Int64,2}

julia> convert(Array{Int64, 2}, s)

我在ionic3中使用延迟加载,但是当它服务时,浏览器会显示错误:

无法导航:找不到TabsPage的组件工厂.你有没有把它添加到@ NgModule.entryComponents？

这是我的代码:

app.module.ts

@NgModule({
  declarations: [ 
    MyApp, 
    FormModal,
    PreviewModal, 
  ],
  imports: [
    BrowserModule,
    HttpModule,
    JsonpModule,
    CommonModule, 
    IonicModule.forRoot(MyApp)
  ],
  bootstrap: [IonicApp], 
  entryComponents: [ 
    MyApp, 
  ],
  providers: [ 
    Router,
    StatusBar,
    SplashScreen,
    ApiService,
    Toast,
    Loading,
    Alert,
    UserService,
    ChangeTitle,
    ParseLogin,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

app.component.ts

@Component({
  templateUrl: 'app.html'
})
export class MyApp {

  rootPage:any = "TabsPage";

  constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen,router:Router) {
    router.setVersion('1.0',10000);
    router.load(Routes);
    Event.subscribe('push',(ev,data)=>{
      document.title =Routes[data.toPage.name].title;
      var i = document.createElement('iframe');
      i.src = 'blank.html';
      i.style.display …

我在java中创建一个哈希表.在搜索功能中,我在IF语句中进行了一些比较.但它没有做任何比较.

这是我的代码的一部分.

while (table[pos]!=null) {
        if (table[pos]==key) {
            System.out.println("SEARCH "+key+" at INDEX "+home);
            return;
        }
        else {pos=h(home+p(i));
        i++;
        }
    }
    System.out.println("Failed to find "+key+".");
    return;
}

即使表[pos]和键是相同的,它也不起作用!但我将非常简单的赋值变量添加到另一个变量.这行得通!我不知道为什么会这样.我想知道它xD

   while (table[pos]!=null) {
        int x = table[pos];
        if (x==key) {
            System.out.println("SEARCH "+key+" at INDEX "+home);
            return;
        }
        else {pos=h(home+p(i));
        i++;
        }
    }
    System.out.println("Failed to find "+key+".");
    return;
}

无论如何，在Ionic 3中使用警报显示新行吗？

我应该用'\ n'代替什么？

doFinalise() {
let confirm = this.alertCtrl.create({
  title: 'Are you sure?',
  message: 'Are these details correct?\n Price ($/L): \n KMs Done: \n Total Spent: \n Fuel Type: \n Date: ',
  buttons: [ etc...

最终，该消息将在新行之前显示变量，但是在此阶段不需要。
