L = \sum_l \left[ a_l \ln \omega_l - a_l \ln a_l + a_l \right] + \alpha \left( N - \sum_l a_l \right) + \beta \left( E - \sum_l \varepsilon_l a_l \right) 对 a_l 求导并令导数为零: \frac{\partial L}{\partial a_l} = \ln \omega_l - \ln a_l ...
编程的时候要注意特殊字符的问题,很多运行时出现的问题都是因为特殊字符的出现而引起的。 注意,由于反斜杠本身用作转义符,因此不能直接在脚本中键入一个反斜杠。如果要产生一个反斜杠,必须一起键入两个反斜杠 (\\)。 编码转换(to Unicode) (程序代码来源于网络) Js版 test = "你好abc" str = "" for( i...
