微带多模谐振器的谐振频率的提取程序，就是在已知线宽，线长和介质基底的情况下如何计算得到其多个谐振频率。学习多模谐振器数值分析的同学可以参考一下。(Multi-mode microstrip resonator resonance frequency extraction procedure is known in the case of the line width, line length and the dielectric substrate to which a plurality of resonance frequencies calculated. Learning multimode resonator numerical analysis of the students can refer to.)

单级机械臂的位置控制，由于需要调整时间和最大输入力矩的要求，程序实现两种非标准的LQR控制(The single-stage manipulator position control, due to the need to adjust the time and the maximum input torque requirements of the program to achieve the two non-standard LQR control)

详细描述了关于几个同时说话人语音分离的情况，其中包括了原代码和测试语音，测试结果表明分离效果很好，能够区分不同人说话的语音，明显提高语音识别率。其中的参考论文在readme中。(A detailed description about several while speaking voice separate conditions, including the original code and test speech, test results show that the effect is very good separation between different people speak of speech recognition, obviously improved pronunciation. One of the reference in the readme.)

This function compute the sun position (zenith and azimuth angle at the observer location) as a function of the observer local time and position.
