matlab 版 数独小游戏 GUI界面设计

近期，由于各种原因，接触到了matlab版的数独小游戏，需要做GUI界面。由于之前本科的时候自己也做过简单的界面涉及，就以为很简单，结果，piapia打脸。数独中的数字是在table中显示的，为了将题目数字，作答数字、答案数字和解答数字区分开，需要设置不同的颜色，但是网上相关资料太少，所以这个界面设计过程很痛苦，现将个人经验分享于此。

首先是数独游戏的解法，这个网上一搜一大堆，本文所用程序与如下网址中所述一致。

数独生成部分没使用算法自动生成，而是根据网上资料手动输入了30组数独题，放到了data.txt中，30*81，其中一行为一个数独题目，使用时将其中一行reshape成9*9矩阵即可。将数独题目分成简单、一般、困难三种模式，根据slider的值进行判断，slider的值在0-1之间，0-0.33时，对应简单模式，0.33-0.66对应一般模式，0.66-1对应困难模式。生成数独时，根据slider的值找到对应模式，然后在对应模式中随机抽取题目即可。

然后就是比较关心的不同字号显示问题了，这里用到了html，举一个栗子~

CurCell{row,col}=['

','',num2str(CurMat(row,col)), '

CurCell是cell类型的数据，用于在table中显示，row和col分别对应其行数和列数，bgcolor="white" 用来设置背景颜色，text-align:center设置居中显示，FONT face="Times New Roman"设置新罗马字体，size="25"，设置显示的字号为25，color=green"用来显示字体颜色为绿色，这里是手动输入的字体颜色。

其实懂了就很简单了，但是由于网上资料较少，所以找了很久也没有找到，所以，就想分享给有需要的人们呦。

代码如下，因为涉及到UI界面的tag等，所以如果想直接运行也可直接下载我的matlab程序哦
