ov9710/ov9715是ov公司开发的2Mega像素的cmos芯片，支持1080P分辨率的视频。本资料包含两款芯片的官方编程应用手册（application notes）,非datasheet(ov9710/ov9715 is developed 2Mega ov pixel cmos chips, support for 1080P resolution video. This information contains the official application programming chips Manual (application notes), non-datasheet)

Apply the Lanczos filter to a real time series, in the frequency space, i.e., using FFT which is faster than applied as a cosine filter in the time space.

以二体问题为模型，从地球发射航天器探索火星，途中需经过一次无动力金星借力，寻找最优（总速度增量最小）的发射时间窗口和飞行时间，并绘制地球到金星的Pork-Chop发射能量等高线图。发射时间窗口为2023—2033年，总飞行时间不得大于2年。(Taking the two body problem as the model to explore Mars from the earth, it is necessary to seek an unpowered Venus transit force on the way to find the optimal time window and time of flight (the minimum total velocity increment), and draw the contour map of the Pork-Chop emission energy of the earth to Venus. The total launch time window is from 2023 to 2033, and the total flight time is not more than 2 years.)

matlab神经网络代码(Matlab neural network code)

生成一个采样频率2000，由50Hz、120Hz、200Hz正弦信号以及噪声信号组成的数字信号，滤掉150Hz>f>100Hz的频率，计算并显示滤波前后的原始数据波形以及功率谱密度。(A sampling frequency of 2000, a digital signal composed of 50Hz, 120Hz, 200Hz sine and noise signals, is generated to filter out the frequency of 150Hz>f>100Hz and to calculate and display the original data waveforms and the power spectral density before and after the filtering.)

说明：  基于MATLAB的Filter使用，低通、带通和高通滤波器的仿真。包括filter、ftt等函数的使用(Matlab based filter use, low-pass, band-pass and high pass filter simulation. Including the use of filter, FTT and other functions)

基于matlab的摸拟退火算法研究（很经典）(Based on the simulation annealing algorithm matlab Study (classic))

三相逆变器仿真模型，dq解耦控制，SPWM，包含MPPT算法。(three phase inverter model, dq control, SPWM, MPPT included.)
