为什么好多自带的示例文件都有点像乱码一样， 到处是斜杠、感叹号、\N……什么的！
如下：
//! -# This program calculates: \b **freqhz_fr** \n //! \f[ freqhz\_fr\ or\ v = \frac{x_{2}-x_{1}}{T} .......... 1 \f] \n //! If \f[ \frac{max}{base}\ freq = 10kHz => 10kHz = \frac{x_{2}-x_{1}}{(2/100Hz)} .......... 2\f] \n //! \f[ max (x_{2}-x_{1}) = 200 counts = freqScaler\_fr \f] //!
