用Matlab实现在线音乐试听，有趣的小程序(listen to music online by Matlab, an interesting applets)

用于求解高速球轴承的非线性方程组，输入主程序，用fsolve，可以直接解出来(Nonlinear equations used to solve high-speed ball bearings, input the main program, with fsolve, can be solved directly.)

VC实现对MATLAB的调用，对于研究二者混合编程的人比较有用(VC++ implementation of the MATLAB call for the mixture of the two studies were more useful for programming)

说明：  <信号分析与处理：MATLAB语言及应用> 本书将信号分析与处理、信号与系统、与matlab语言紧密结合。提供大量matlab应用程序(err)

温度模型 需要的可以直接拿走 但是没有说明(Temperature model may need to take but did not say directly)

短时FFT变换，用于数字信号的时频分析，可以加不同的窗函数。(Short time Fourier transform)
