很多学者梦寐以求的MATLAB带界面的滤波程序(Many scholars dream of MATLAB with the interface of the filtering process)

说明：  “水仙花数”是指一个三位数，其各位数字的立方和等于该数本身。用两种不同的方法求所有的“水仙花数”。 ("narcissi few" refers to a triple-digit, the number of cubic you and equal to the number itself. Using two different methods for all of the "Narcissus few.")

因而本文基于MATLAB 针对Nakagami 衰落信道仿真了它的统计 特性,包括接收信号的复包络模拟和在具有最大比合并分集下的电平通过率及平均衰落持续时间的性能分析。重点在于理解和建立采用 MATLAB 进行信道信真的方法及对Nakagami 衰落信道本身统计特性的理解。(Based on MATLAB which Nakagami fading channel simulation for its statistical properties, including the received signal complex envelope simulation and has the maximum ratio combining diversity under the level crossing rate and average fade duration of the performance analysis. Emphasis is on understanding and the establishment of the channel using MATLAB and the letter is really way Nakagami fading channel statistical characteristics of their own understanding.)

用Matlab仿真的基于DRFM的等间隔直接转发干扰，内有时域和频域分析。(Matlab simulation with equal intervals based drfm forwarded directly interfere, sometimes within a domain and frequency domain analysis.)

说明：  由通用桥式电路模块组成的单相晶闸管组成的单相晶闸管整流电路(By the universal bridge circuit single phase thyristor modules consisting of single-phase thyristor rectifier circuit)

Goal of the project was to use numerical methods for solving systems of ordinary differential equations (ODE) using MATLAB software. As in previous assignments first of all I had to research for algorithms, which would be helpful during evaluation of each task, later on I was able to implement and test numerical methods for solving given problems. Each student received electric circuit containing different elements to solve. Each task is presented under separated heading, with its full description, problem discussion, my approach for solving it and explanation.

一个单位负反馈系统的滞后超前频域法校正，可直接在matlab中打开和运行(A unit negative feedback system lag correction ahead frequency domain method can directly open and run in matlab)

用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。(用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。自动检测中英文中译英英译中百度翻译. 翻译结果（中 > 英）复制结果 Using Romberg method for integral calculation accuracy, while cycle number less than 10, operation more convenient, fast calculation before, given the need for function expression, integral upper and lower as well as the error range.

说明：  太阳能电池板的模拟，来自阳光电源测试部，存在缺陷，请多指教(Simulation of solar panels, sun power test from the Ministry of flawed, Pleased to meet you)

Identifying overlapping period in time series. Required input: X = structure with in every cell (X{cell}) a measurement station. every cell has its first three columns as [year,month,day] Output: begin_date = is beginning date of overlapping periods end_date = end date of overlapping periods output = structure with overlapping periods filtered numcell = number of measurement stations
