对已知信号进行SSB调制，然后观察其频率域特性(Known signal SSB modulation, and then observe its frequency domain characteristics.)

利用神经网络进行语言特征的识别，很有用的代码，希望对大家有用(Neural network is used to identify the characteristics of language, is very useful code, hope useful for everyone)

interval dessombz and some other methos to solve linear Ax=b.

说明：  分数阶热传导工具箱可以用于求解分数阶微分方程中的热传导过程的求解，包含解析解与数值解的求解方式，含有显式，隐式和Crank–Nicolson求解方法。(The methods of solving models of heat conduction are described, namely analytical and numerical methods. In the case of numerical methods regards the finite difference method by using GL definition for the fractional time derivative. Implementation of these individual methods was realized in MATLAB. The two libraries of m-functions for the heat conduction model have been created, namely Heat Conduction Toolbox and Fractional Heat Conduction Toolbox.)
