爱华网下面是Matlab官方列出来的Tex代码列表，包含了绝大部分的希腊字母和数学符号。
这个比较清楚

文档中的Text Properties:
下标用_(下划线)上标用^ （尖号） 斜体it黑体 bf；
比如在坐标轴的[0.5 0.5]位置上要显示δ字符，那么可以直接输入text(0.5,0.5,'delta')
如果需要显示大写希腊字符的话，那直接将首字母改为大写就可以了；
注意必须使用“”引导，如果需要显示“”，那么必须输入“\；
类似的在字符串组合的时候如果要输入“'”则必须如下输入“''”；
另外text字符可以重叠显示，这样就可以构造出一些有趣的效果，比如将某个字符上添加一个斜杠或者画一个叉等。
