MATLAB显示工作区元素的链接 [英] MATLAB display a link to workspace elements

问题描述

我正在尝试提高输出的可读性.为了避免显示大量数据，最好显示指向工作空间中特定元素(即变量，表格，图形等)的链接.

I'm trying to improve the readability of my outputs. In order to avoid displaying a lot of data, it would be nice to display links that point to specific elements in the workspace (i.e. a variable, a table, a figure, etc.).

下面是一张图片来说明这个想法:

Here is a picture to illustrate the idea:

也许我们可以使用disp函数，因为我知道它可以生成指向网页或存储在计算机中的文件的超链接.

Maybe we can use the disp function, as I know it allows the generation of hyperlinks to a webpage or a file stored in the computer.

在MATLAB中有可能吗?

Is this possible in MATLAB?

推荐答案

好的，这就是我的想法.首先是使用 openvar 函数，然后指定要用单引号引起来的变量.这将在变量编辑器"(快照中显示的图像)中打开变量.

OK, so this is what I came up with. The first thing is to use the openvar function and you specify the variable you want wrapped around in single quotations. This will open up the variable in the Variable Editor (the image that is pictured in your snapshot).

现在，您还可以使用disp 允许可点击的链接运行MATLAB命令.使用这两个想法，可以将disp链接和openvar组合在一起，以允许可单击的链接执行openvar函数以显示所需的变量.

Now, you can also use disp to allow clickable links to run MATLAB commands. Using these two ideas, you would combine the disp linking and openvar to allow a clickable link to execute the openvar function to display your desired variable.

这样，您基本上会假设我们的变量存储在A中:

As such, you would basically do this assuming our variable is stored in A:

A = magic(5);
disp('<a href="matlab:openvar(''A'')">Click on me to show the matrix A</a>')

disp语句将为您显示一个可单击的链接，并且只有在您单击链接后才能运行所需的要执行的功能.您可以通过在href键的URL中指定matlab:关键字来实现此期望的效果，然后在其后写出要使用的任何MATLAB函数或语句.在我们的例子中，我们只需要运行一个函数，那就是openvar.确保在openvar的参数内要在变量周围指定单引号.原因是因为disp的参数是一个字符串，并且如果要识别单引号，则必须使用一对单引号.这样，在disp字符串中，您想要的变量周围有一对单引号.

The disp statement will show you a clickable link, and the desired function to be executed only runs if you click on the link. You can achieve this desired effect by specifying the matlab: keyword inside the URL in the href key, then after it, you write out whatever MATLAB function or statements you want to use. In our case, we use only need to run one function, and that's openvar. Make sure you specify single quotes around the variable you want inside the argument to openvar. The reason why is because the argument to disp is a string, and if you want single quotations to be recognized, you must use a pair of single quotes. As such, in the disp string, there are pairs of single quotes around the variable you want.

这是我在MATLAB中得到的.复制这些步骤并以GIF动画形式对其进行显示:

Here's the what I get in MATLAB. The steps are reproduced and shown in an animated GIF:
