SharpSharpSharp3D_Reconstruction

Matlab学习资料，包括MATLAB基础教程、matlab实用教程、精通Matlab6[1].5(张志涌)等(Matlab learning materials, including MATLAB Basics Tutorial, matlab practical course, master Matlab6 [1] .5 (Zhang Yong), etc.)

Matlab讲义高级.rar，PPT课件(Matlab senior notes. Rar, PPT Courseware)

matlab用于参数估计的代码 可以处理数据分析 方便拟合(matlab code for parameter estimation can handle data analysis)

这是我另一个同学的关于图像处理与机器学习的作业，对四组图像提取特征值，进行分类识别。LIBSVM.文件里包含代码，及一些参数调试。(This is another of my classmates on image processing and machine learning operations on four sets of image feature extraction values ​ ​ for classification. LIBSVM. File contains the code, and some parameters debugging.)

principal component analysis applied to an image

Fs = 100000 t = 0:1/Fs:.00296 x = 1-cos(4*pi*t) cos(2*pi*t*200) h = spectrum.welch Instantiate a welch object. psd(h,x, Fs ,Fs) Plot the one-sided PSD

 利用fft()进行快速傅立叶变换，得到频谱，画出正弦函数及其频谱  找出频谱中使得Y轴取最大值时的估计频率记为ft  加入白噪声，绘出信噪比和均方误差的关系曲线 ( using fft () for fast Fourier transformation, spectrum, to draw the sine function and its spectrum  find the spectrum makes the Y-axis maximum value when the estimated frequency is denoted by ft  adding white noise, SNR plot and mean square error curve)

说明：  it is a three-phase PWM inverter

这是MATLAB工具箱，用来实现波形的生产！(This is the MATLAB toolbox, which can be used for the production of wave!)

说明：  matlab 的一个洗牌算法，调用固定区间的随机数生成，然后根据随机数序列交换位置，达到洗牌效果(Matlab call a random number generate function then exchange the numbers according to the random numbers)
