正弦信号的频谱分析，希望可以帮到各位！祝各位学习语愉快！(good morning ！good afternoon ！good evening！good night！)

基于高阶累积量的调制识别matlab源码，该算法可以对常用的2ask,2psk,2fsk,4ask,4psk,4fsk信号进行识别，准确率高。(high-order cumulants modulation recognition 2ask,2psk,2fsk,4ask,4psk,4fsk)

分析了弹道仿真数学模型的特点、并以滑翔增程弹为例，详细研究了在M文件、simulink工具箱以及两者交互使用环境下建立外弹道质心运动系统仿真模型的方法和优缺点。 (Analysis of the ballistic characteristics of the mathematical model simulation and Gliding Range shells as an example, a detailed study of the M paper, simulink toolbox and use both interactive environment to establish external ballistics center of mass movement system simulation model and the advantages and disadvantages.)

无约束一维极值问题，进退法，黄金分割法、奜波那契法，牛顿法，割线法，goldstein法，wolfe-powell 算法matlab源代码(Unconstrained a d extremum problems, in a method, the golden section method, wave that contract law, Newton method, secant line rule, goldstein method, Wolfe-Powell algorithm matlab source code )

利用Matlab实现电压突降信号的仿真，通过Hilbert变换、快速傅里叶变换来实现。(Using Matlab simulation for voltage sags signal through Hilbert transform, fast Fourier transform to achieve.)

说明：  双电机模型用于汽车的搭载和嵌入，与其他汽车模型联合使用(The dual motor model is used for vehicle loading and embedding, and is used in combination with other vehicle models)

Matlab工具仿真，经典MUSIC算法，一次性得到多个信号的DOA估计参数(using matlab tool and classical MUSIC mathod,to get doas for multiple signals. good.)

In this code we use the technique of keyword spotting to search in the spoken document

这个例子里，我们将独立(白噪声)样本通过有5dB通带纹波的切比雪夫滤波器。 试估计滤波器输出端的PSD。实现这一估计的MATLAB程序如下: (This example, we will be independent (white noise) samples through a 5dB passband ripple Chebyshev filter. Estimate the filter output PSD. MATLAB program to achieve this estimate is as follows:)

本例用五点差分法求解一个二阶偏微分方程，其间用Jacobi迭代求解(This example uses a five-point difference method for solving second order partial differential equations, during which the Jacobi iterative)
