说明：  设计中心波长在1550nm,光栅长度、折射率调制深度等可调，可以仿真出FBG的透射谱(The design center wavelength is 1550 nm. The grating length and refractive index modulation depth can be adjusted.The transmission spectrum of FBG can be simulated.)

this is a matlab code for computing DTW(dynamic time warping) for speech processing applications.

说明：  AC induction motors are the most common motors used in industrial motion control systems, as well as in main powered home appliances. Simple and rugged design, low-cost, low maintenance and direct connection to an AC power source are the main advantages of AC induction motors. The speed control of these motors has been of great importance in order to run the motors at desired speeds. Among the various methods of speed control V/F control of induction motor is the most efficient one, in which V/F ratio is kept constant. In this project we studied about this V/F control of an induction motor and simulated it in the matlab Simulink and controlled the torque and speed of induction motor. This technology continued to be taken up further improvements all over the world till very recently.

matlab上倒谱的两种实现方式。一个是调用rceps（）函数来实现，另一个是根据定义来实现。两种方法画出的倒谱图一样。 附件中包含要处理的数据，该数据为加速度数据。(matlab on the cepstrum of two implementations. One is called rceps () function, and other is by definition to achieve. Draw the two methods as the inverted spectrum. Annex contains data to be processed, the data for the acceleration data.)
