Matlab 参数化绘图 GUI - 通过滑块改变参数
我经常有这样的功能：
sin(a*w*t + p)
where:
w = natural frequency
t = time
a,p = parameters (which I can vary)
正如你所看到的，如果你想改变a,p，你可以通过标准接口来做到这一点，但它不是很方便。所以我想我应该寻找一个 GUI，每个参数都有一个滑块。这样的事存在吗？
我从未见过，所以我想我应该尽快写一篇。然而，我担心由于缺乏时间和对 matlab 的了解，我会导致诸如移动滑块时生成太多绘图命令而不是仅一个等问题。当然，我也有一个问题，我想指定一个字段，用户可以在其中指定函数，例如通过在文本字段中键入 sin(a*w*t +p) ，然后指定每个变量的含义，而我目前不这样做不知道该怎么做（它看起来像一个解析任务）。我可以这样做还是应该使用一组预定义的函数？
I often have function such as:
sin(a*w*t + p)
where:
w = natural frequency
t = time
a,p = parameters (which I can vary)
As you can see if you want to vary a,p, you can do so via the standard interface but it's not very convenient. So I thought I'd look for a GUI which has a slider for each parameter. Does such a thing exist?
I've never seen one so I thought I'd quickly write one. However, I'm worried that due to lack of time and knowledge of matlab I will cause problems such as generating too many plot commands when the slider is moved instead of just one. Of course I also have the problem that I want to specify a field where the user can specify the function e.g. by typing sin(a*w*t +p) in a text field and then specify what each variable means which I currently don't know how to do (it looks like a parsing task). Can I do this or should I go with a predefined set of functions?

您可以在 Matlab File Exchange 中找到类似的项目作为示例。
例如：
我没有看代码但根据屏幕截图，它应该对您有帮助。
关于函数输入功能，您可以使用函数
eval（如果需要可靠性，可以对输入进行一些检查）。如果您想允许任何参数变量，可能会更困难。You can find similar projects in Matlab File Exchange as example.
For instance:
I didn't have a look at the code but according to the screenshots, it should help you.
Regarding the function input feature, you can use the function
eval(with a few checks on the input if you need reliability). If you want to allow any parametric variable, it may be harder.
