因为疫情，在家（无聊）想着看一下Matlab App Builder，花了一点时间，做了个简单的计算器。只做了基本的计算功能，算是对Matlab App Builder的一个基本的学习。
Matlab App Builder比起成熟的一些制作app的语言来说，功能非常简陋，不过也非常好上手，如果对Matlab基本语言很熟悉的话，可以说，上手基本没有什么障碍。因为Matlab App Builder的程序可以直接打包成exe，所以如果不想去搞window程序开发，而又想制作一些简单的程序的话，这个Matlab App Builder看起来是一个比较不错的工具。（虽然打包成exe之后效率很低，嘿嘿）
制作这个简单的（弱智的）计算器，最大的工作量就是在判断输入逻辑上，比如说：
- 连续输入两个’.’，那么后面一个’.’要忽略掉；连续输入两个‘+’，后面一个‘+’要忽略掉；
- 按下‘+/-‘键取反的时候，需要先判断当前输入的数据，如果不是数据，则忽略，是数据的话，取反并显示；
- 按下’sqrt’时，后面的输入需要写进括号里面；删除的时候也要考虑这一点。
其实大量的实践都花在这样一些输入逻辑上了。最后做成的样子是这样：
基本的功能实现了，但是也有很多的bug。
代码如下：
