下面给出Matlab中下标及希腊字母的使用方法,还有更多的使用方法可以参考matlab帮助
文档中的Text Properties:
下标用 _(下划线)
上标用^ (尖号)
斜体 \it
黑体 \bf
<< \ll
>> \gg
正负 \pm
左箭头 \leftarrow
右箭头 \rightarrow
上箭头 \uparrow
上圆圈(度数) \circ
例 text(2,3,'\alpha_2^\beta')
或者text(2,3,'\alpha_{\beta\mu}')
it\w(x):mm,要求w(x)是斜体,而:mm不要求斜体
{it\w(x)}:mm把要设置成斜体的用大括号放在一起
注: 可用{}把须放在一起的括起来
特殊的数学符号
\approx
\times
箭头
\uparrow ↑
在图形的坐标处书写文字注释
x=0:0.2:2*pi;
y=sin(x);
plot(x,y)
text(2,sin(2),'wacs5');
