基于锁相环Top-down的建模方法在MATLAB环境下建立数字锁相环完整的仿真模型，并用SIMULINK对数字锁相环的仿真模型进行仿真。　(Top-down phase-locked loop based on the modeling method in MATLAB environment DPLL set up a complete simulation model, and use of digital phase-locked loop SIMULINK simulation model simulation.)

振动工具箱，源代码，有目录及详细说明，希望对大家有用(Vibration toolbox, source code, there are directory and detailed description, in the hope that useful)

自己写的MATLAB程序，用于已知2个单位向量，求它们的旋转矩阵。非迭代法。 另有一个绝对定向程序。(Write their own MATLAB for 2 unit vector, known for their rotation matrix. The iterative method. There is another absolute orientation program.)

利用MATLAB绘制北极海冰密集度图，海冰密集度0—100 （海冰密集度数据下载NSIDC）(Draw the intensity map by MATLAB Hai Bing, Hai Bing (Hai Bing 0- 100 intensive intensive data download NSIDC))

emd分解，通过emd分解重构信号实现降噪(By the emd decomposition reconstruction signal noise reduction)

FIR滤波器，实现了消除心电信号中的杂音。(FIR filter, to achieve the elimination of noise ECG.)

目标和雷达的仿真程序，可以设置目标位置向量、速度、目标散射截面积、距离门限等等，计入高斯噪声，经过混频和傅里叶变化后再显示其距离和多普勒二维图形。(Target and radar simulation program can be set to the target position vector, velocity, target scattering cross-sectional area, the distance threshold, etc., included in the Gaussian noise, and then after mixing and Fourier transform show its range and Doppler two-dimensionalgraphics.)

根据归一化后的原始数据曲线，进行导数变换，然后运用自组织神经网络进行藻种识别(According to the normalized data,we use the Differential switch,and then identify the HABs using the SOM.)
