在SENSE成像中如何将中间图像转化为最终图像，就要用到这个程序(Using specfied sampling vector to generate a 2D aliasing matrix. The sampling vector is a vector of n-entries of either 0 or 1, where 0 indicates no k-space line acquisition and 1 indicates k-space line is acquired in the accelerated scan. For example, a sampling vector of [0 1 0 1 0 1 0 1 0 1] indicate the 2-fold acceleration with 8 phase encoding lines. The aliasing matrix is calculated based on Fourier imaging)

本文介绍了直接序列扩频系统中数字Costas环的设计与实现，用来实现载波同步的闭环算法(This paper introduces the direct sequence spread spectrum digital Costas loop in the design and implementation to achieve closed-loop carrier synchronization algorithm)

Matlab提取主分量矩阵。程序设计步骤： 1、去均值 2、计算协方差矩阵及其特征值和特征向量 3、计算协方差矩阵的特征值大于阈值的个数 4、降序排列特征值 5、去掉较小的特征值 6、去掉较大的特征值(一般没有这一步） 7、合并选择的特征值 8、选择相应的特征值和特征向量 9、计算白化矩阵 10、提取主分量()

对花卉的数据集分别通过“五折法”、随机产生训练样本、欧式平方距离、绝对值距离、契比雪夫距离和马氏距离进行数据集的识别。(Data sets, respectively, for flowers through the " half of Law" , randomly generated training samples, European squared distance, absolute distance, Chebyshev distance and Mahalanobis distance for data set identification.)

说明：  求瞬时频率必不可少，MATLAB系统不自带的，下载后放在MATLAB到toolbox，然后在EMD文件夹下，更新MATLAB路径即可。运行emd即可出现频谱分析图。(It is necessary to find the instantaneous frequency. The MATLAB system does not come with it. After downloading, it is placed in the MATLAB to toolbox. Then, under the EMD folder, the MATLAB path can be updated. The spectrum analysis diagram can appear when EMD is run.)

说明：  近10年来的大量研究充分肯定了自主神经活动与心血 管疾病死亡率特别是猝死率之间的关系。同时也公认心率变 异(HRV)是判断自主神经活动的最好的定量指标(Nearly 10 years of extensive research activities in full recognition of the autonomic nervous and cardiovascular disease mortality rate in particular, the relationship between sudden death. Heart rate variability also recognized (HRV) is the best judge of autonomic nervous activity quantitative index)

这是一个隐马尔可夫模型前向算法，各位亲可以下载使用，一般用于计算分类，预测，等等(This is a hidden Markov model before the algorithm, you can download pro, generally used to calculate the classification, prediction, etc.)
