MATLAB应用大全一书的配书光盘第四章源代码,该文件夹收录了本书涉及的源文件。收录了一些优秀应用实例信息，便于读者学习了解。(MATLAB application of CD attached with books in the fourth chapter of the source code, this folder contains the book files. Includes some excellent examples of application information, convenient for readers to learn. )

计算方法中得romberg算法，matlab编程(Calculation method was romberg algorithm, matlab programming)

分析了该信号的时域、频域、倒谱，循环谱等,结合PCA的尺度不变特征变换(SIFT)算法，DC-DC部分采用定功率单环控制。( Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Combined with PCA scale invariant feature transform (SIFT) algorithm, DC-DC power single-part set-loop control.)

在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。(In process control, according to the ratio of deviation (P), integral (I) and differential (D) to control the PID controller (also known as PID regulators) is the most widely used an automatic controller.)

求给定初值问题的数值解 用了龙格库塔和欧拉发解的(Demand for a given initial value problem with the Runge-Kutta numerical solution and the solution of the Euler made)

鲁棒性好，性能优越，有PMUSIC 校正前和校正后的比较，数值分析的EULER法，采用了小波去噪的思想，包含了阵列信号处理的常见算法，感应双馈发电机系统的仿真。( Robustness, superior performance, A relatively before correction and after correction PMUSIC, EULER numerical analysis method, Using wavelet denoising thought, Contains a common array signal processing algorithm, Simulation of doubly fed induction generator system.)

自适应的最小均方算法：只要自适应线性组合器每次迭代运算时都知道输入信号和参考响应，选用LMS算法很合适。(Adaptive least mean square (LMS) algorithm: as long as the adaptive linear combiner for each iteration when they know that the input signal and reference response, selection of LMS algorithm is very appropriate.)

算地震动，加速度，位移和速度，很好用的，呵呵。大家给力啊。(Considered ground motion, acceleration, displacement and velocity, the good, huh, huh. We can give power ah.)
