说明：  核密度估计(kde)的工具箱,来源于 Copyright (C) 2003 Alexander Ihler(The KDE class is a general matlab class for k-dimensional kernel density estimation. It is written in a mix of matlab ".m" files and MEX/C++ code. Thus, to use it you will need to be able to compile C++ code for Matlab. Note that the default compiler for Windows does not support C++, so you will need GCC under Linux, or GCC or Visual C++ for Windows. Bloodshed supplies a nice development environment along with the MinGW compiler. See this page for help setting up MEX with MinGW.)

说明：  多小区、多用户蜂窝小区的建模。其中每个小区内设置一个基站，以基站为圆心，以一定半径在基站附件分布n个用户。可直接运行(Modeling of multi-cell and multi-user cellular cell. A base station is set up in each cell, with the base station as the center, and N users are distributed in the base station accessories with a certain radius. Direct operation)

说明：  传统的相控阵雷达，发射信号完全相关，通过对每个阵元加不同相移就可以改变波束的发射方向。以这种方式形成的波束通常主瓣较窄，信噪比比较高，若用于跟踪方向先验已知目标或只对空间某一窄的领域进行搜索时非常有利。本代码可以实现正交波束的形成.(In the traditional phased array radar, the transmitting signal is completely correlated, and the transmitting direction of the beam can be changed by adding different phase shifts to each array element. The beam formed in this way usually has a narrow main lobe and a high signal-to-noise ratio. This code can realize orthogonal beam forming)

说明：  实现风能MPPT功能，可在模型上进行故障特性分析(Realizing MPPT function of wind energy, fault characteristic analysis can be carried out on the model.)

C语言实现学生管理系统，包含增删改查（CRUD）等功能编译直接使用(C language implements student management system, including add, delete, check (CRUD) and other functions compiled and directly used)

LPC2000系列ARM芯片IAP例程，包括I2C、SD卡、CAN总线、XMODEM升级方式和演示程序(LPC2000 family of ARM chip IAP routines, including I2C, SD card, CAN bus, that XMODEM upgrade and demo program)

应用背景如今机器人已经逐渐在社会某些领域崭露头角，无人机、智能车等机器越来越显示出其独有的优势。本设计实现智能小车在跷跷板上保持平衡。关键技术智能小车采用单片机为MCU，外接了轮子，马达等必要器件，采用C语言编程，能够完成上跷跷板、在跷跷板上保持平衡等的功能。

I want to congratulate you and congratulate you and change my program!!!

一个1MHz的FIR低通滤波器。 ① 时钟信号频率16MHz; ② 输入信号位宽8bits，符号速率16MHz； ③ 要求在Matlab软件中进行FIR滤波器浮点和定点仿真，并确定FIR滤波器抽头系数； ④ 写出测试仿真程序。(A 1MHz FIR low pass filter. (1) The clock signal frequency is 16MHz; (2) The input signal has a bit width of 8 bits and a symbol rate of 16 MHz; (3) Floating-point and fixed-point simulation of FIR filter is required in Matlab software, and tap coefficients of FIR filter are determined. (4) Write the test simulation program.)
