//在Mathematica中是什么意思? [英] What does // mean in Mathematica?

问题描述

示例:

• 在

CT = Table[Prepend[10^4*x[range2] /.
     NDSolve[{...series of equations here...}, {t, range1, range2}, 
        MaxSteps -> 10000,
        PrecisionGoal -> 11], delay], 
        {delay, delaymin, delaymax, 0.1}]; // Timing

分号后的// Timing是什么意思?

• 在

Dρ = -I*((H0 + V).ρ - ρ.(H0 + V)) - Γ*ρ // Simplify;

这里是// Simplify吗?

我在任何地方都找不到这个解释！

I can't find this explanation anywhere!

推荐答案

您说:我在任何地方都找不到这个解释！".我认为这意味着您在使用Mathematica时就不了解指尖附近的文档中心.

You say: "I can't find this explanation anywhere!". I assume this means you are not aware of the documentation center that's right under your fingertips whenever you're using Mathematica.

所有您需要做的就是将光标置于//上并按F1键，您将获得某种解释，或包含相关(希望有)匹配项的列表.在这种情况下，PostFix页不是很有帮助.但是，它的底部有一些链接(假设您具有版本6、7或8)提供了更多的见解，其中包括指向语法概述页面的链接(单击Mathematica语法链接，或在命令行中输入"guide/Syntax").搜索框).

All you have to do is to place your cursor on the // and press F1 and you'll get some sort of explanation, or a list with relevant (hopefully) matches. In this case the PostFix page, which is not extremely helpful. However, it has some links at the bottom (assuming you have versions 6, 7 or 8) that provide more insight, among which a link to the syntax overview page (click the Mathematica syntax link, or enter "guide/Syntax" in the search box).
