Sunspot activity is cyclical, reaching a maximum about every 11 years. Let s confirm that. Here is a plot of a quantity called the Zurich sunspot relative number, which measures both number and size of sunspots. Astronomers have tabulated this number for almost 300 years.

一种光滤波器仿真设计.具有一定局限性.通过先行缔造滤波器频谱图,进行设计仿真(Simulation design of an optical filter has certain limitations. Plan first to create a filter spectrum, to simulate the design)

采用多孔trous算法(undecimated wavelet transform)实现小波变换 (The use of porous trous algorithm (undecimated wavelet transform) the realization of wavelet transform)

小波变换和二维最大类间方差法实现变化检测(Wavelet transform and two-dimensional maximum between class variance method to achieve change detection)

Matlab的FFT算法程序 里面有基2时间抽取的FFT 还有基2频率抽取的FFT (Matlab' s FFT algorithm which has taken the time base 2 radix-2 FFT have taken the FFT frequency)

该程序为matlab源代码，功能为仿真圆环阵的单元选择算法和笔形波束综合(failed to translate)

Matlab双谱分析，高阶累积量的定阶，用相邻奇异值差最大定阶，绘制双谱（等高线图，双谱图，相位图，切片图）(Matlab double spectral analysis, fixed-order cumulant, with the largest difference between adjacent fixed-order singular value, drawing double spectrum (contour maps, dual spectra, phase diagram, slices))

matlab编写的图像光流计算程序 基于块匹配法的全搜索 菱形搜索等各个搜索算法 以及最小绝对误差准则(matlab prepared based on the image optical flow calculation program full search block matching diamond search and other search algorithms and minimum absolute error criterion)

说明：  在matlab平台上，实现对数据的平滑、去噪处理，得到平滑后的数据。(On the MATLAB platform, the data can be smoothed and denoised to get the smoothed data.)

全选主元消元法解方程组，通过测试，可以自己修改方程组(Select principal component elimination method solution of equations)
