So, one way we could look at it is by looking at this density dot diagram, where the density of the dots correlates to the probability density.
其中一个理解它的方法,就是通过看这个密度点图,这里点的密度,和概率密度想关联的。
All right, c p 1 dot y, x I've said assign that to the value 2, 2,0. So now c p 1 has inside of it an x and y value.
一个特定的版本,我现在命名了一个内置变量,并给它赋值了,我刚刚做的也就是给它。
And the idea is that when you do these Lewis dot structures, we're representing electrons with dots, which we'll see in a minute, and each dot is going to represent a valence electron.
而当你遇到这些路易斯点结构时,我们会将电子用点来表示,我们马上就会看到,每个点都代表了一个价电子。
hi3 Whereas Hi3, I just created, it happens to live in this directory but my computer doesn't know that so you do dot slash which says current directory.
至于我刚刚创建的,它正好位于我电脑不知道的位置,所以你必须敲入,/,这代表当前目录。
And you see that the dot intensity grows as you get closer and closer to the center.
点的密度随着到中心的距离,缩短的变密。
I'm going to see if I have enough money to do this in class When we played this game in the old days, during the dot com boom with the MBA students, you had to put fifty dollars on the table to get them interested.
我看看我有没有足够的现金,在之前和MBA学生做这个游戏的时候,那时候正赶上互联网大繁荣,你得拿出来50美元他们才有兴趣
One thinks, in a way, of Welles' line in The Third Man : when he looks down from above and says, "If I gave you 20,000 pounds for every dot that stopped moving, "? would you really tell me to keep my money?"
从某一层面看来,可以假想,Welles,在《黑狱亡魂》中的台词,当他从高处往下看并说,“如果你干掉一个在下面走动的人,我就给你,20,000,英镑,你拒绝得了吗“
uniform So here, I'm going to look at the thing random dot uniform, for example, between minus volatility and plus volatility.
所以在这里,我会看到random。,比方说,在-浮动性值+浮动值之间。
So p dot Cartesian is a kind of accessor, it's getting access to the data.
这就是为什么,我想要使用访问器的原因。
So the first thing it does, price=0 is it says, if self dot price is 0, I'm just going to return.
所以它做的第一件事就是,如果self。,我就返回。
If I want to get values back out, p I could in fact simply send to that instance a message, in this case I could say p dot x.
我就是,我刚刚在这里输入的,我得到了一个c,point的实例,如果我想把值取出来,实际上我可以。
Because what I want to do is, 01 say if self dot price is less than 0.01, 0 I'm going to set it to 0, just keep it there.
因为我想要做的是,比方说如果self。price小于0。,我就把它的值设为,然后放在那。
stdio c So somewhere there's standard IO dot C, stdio h somewhere they're standard IO dot H, but, for me, right now, the only file I need to know about is the dot H, -- because what Sharp include really does -- it's what's called a preprocessor directive.
所以某个地方有一个,现在对于我来说它们是,我只要知道那个,h文件,因为Sharp包含的-,叫做预处理指令。
The convention is not to call it something dot txt but something dot C, just a convention.
但这个文件并不是以XX,txt命名,而是以XX,c命名,这只是一种约定而已。
So ignoring the lambda, what do we expect random dot uniform to do?
先忽略入,我们希望random。uniform会做些什么呢?
I have connected to the course's central server from my own laptop and via dot slash chart am I about to run a little program that depicts as best we can with what with generally call ASCII art -- -- it's really all you can do in a terminal window like this -- our numbers from the past few years.
我已经通过我的电脑连接到了课程的中心服务器,在我的笔记本电脑上,通过键入“,/chart“,我将要运行一个被描写成,“ASCII码艺术“的小程序-,在一个这样的终端窗口中你们都可以做到-,过去几年中我们的人数。
Now we have the dot notation to avoid name conflicts.
现在我们要使用圆点标记法。
