FFT的频谱信号分析Matlab示例程序

pso算法在matlab上实现，对毕业设计有用！现在对做这方面工作的学生有一定帮助 (pso算法在matlab上实现 )

最小二乘辨识系统模型参数的算法，可以用于辨识离散模型的参数(Least squares algorithm for model parameter identification system can be used to identify the parameters of the discrete model)

说明：  PSO源程序，可以任意优化两维数据点和多维数据点，在优化多维数据时，要将初始矩阵变成多维矩阵(PSO source code, you can optimize an arbitrary two-dimensional data point and multi-dimensional data points, in the optimization of multi-dimensional data, to the initial matrix into a multi-dimensional matrix of)

拉个朗日插值公式是把Pn（X）的构造问题转化为n+1插值基函数问题的构造！此软件就是拉哥郎日插值的原程序matlab版(Rafah Colon day interpolation formula is Pn (X) issue of the structure into an n-interpolation function of the structure. This software is Barayagwiza few days interpolation procedures for the original version of Matlab)

matlab入门教程，适合新手，带你快速入门(matlab introductory tutorial for beginners with you Quickstart)

可以在matlab图的下方给出图像标注。matlab的title命令只能在图像的上方标注图标(in Matlab is at the bottom of the map image tagging. Matlab can order the title in the above image tagging icon)

这里我们针对三级固体火箭进行研究，主要考虑每一级发动机工作时推力 和比冲 与发动机试车存在摄动偏差（相差 ）时所产生火箭关机点时刻的状态偏差。火箭的飞行的动力学方程可建立在地面发射坐标系中，火箭的第一级、第二级和第三级按照固定的俯仰角程序飞行，第二、三级飞行时已在大气层外，此时可忽略气动力的影响。(Here we study for three solid rocket, the main consideration at every level when the engine thrust and state arising the moment the rocket off point perturbation deviation (difference) in the presence of specific impulse and engine test bias. Outside of the rocket flight dynamics equations can be established on the ground coordinate system launch, the rocket s first stage, the second and third stages according to a fixed elevation angle of flight procedures, and the second, when the third flight already in the atmosphere, this when can ignore the effects of gas dynamics.)

这个实例是基于传递函数在simulink平台上的建模，是以多环控制系统为例来验证的。里面涉及到各种参数的设置，同时还提到了如何通过simulink原理图得到系统的状态方程，以及输出波形。(This example is based on simulink transfer function modeling platform, is more for the control system as an example to verify.)

Wireless Sensor Networks (WSNs) are comprised of thousands of sensor nodes, with restricted energy, that cooperate to accomplish a sensing task. Various routing Protocols are designed for transmission in WSNs. In this paper, we proposed a hybrid routing protocol: Zonal-Stable Election Protocol (Z-SEP) for heterogeneous WSNs. In this protocol, some nodes transmit data directly to base station while some use clustering technique to send data to base station as in SEP. We implemented Z-SEP and compared it with traditional Low Energy adaptive clustering hierarchy (LEACH) and SEP. Simulation results showed that Z-SEP enhanced the stability period and throughput than existing protocols like LEACH and SEP.
