Numerical Analisys in HP 50 G

说明：  主成分分析(PCA)是多元统计分析中用来分析数据的一种方法,它是用一种较少数量的特征对样本进行描述以达到降低特征空间维数的方法,(Principal Component Analysis (PCA) is a method used to analyze data in multivariate statistical analysis. It uses a small number of features to describe samples in order to reduce the dimension of feature space.)

可以隐藏信息和读取。用LSB算法的。代码长度不长。VC++环境下(to hide information and read. LSB algorithm used. Code length is not long. VC environment)

这是一种用C实现的(2,1,7)卷积码维特比译码算法的软件实现.(This is an achievable with C (2,1,7) convolutional code Viterbi algorithm software.)

基于c语言的单片机控制电机及矩阵键盘控制，适用于单片机初学者(MCU control motor and matrix keyboard)

说明：  用c语言实现电机仿真－基于恒定磁链的转子磁链控制。(Using c language realize electrical simulation- based on a constant flux of the rotor flux control.)

一个好玩的连连看游戏，用Visual Basic 语言开发，我只完成了基本代码，请多多指教。(Lianliankan a fun game, developed in Visual Basic language, I only completed the basic code, exhibitions.)

为了了解系统的资源分配情况，假定系统的任何一种资源在任一时刻只能被一个进程使用。任何进程已经占用的资源只能由进程自己释放，而不能由其他进程抢占。当进程申请的资源不能满足时，必须等待。因此，只要资源分配算法能保证进程的资源请求，且不出现循环等待，则系统不会出现死锁。 要求编写系统进行资源调度的程序，采用银行家算法，有效地避免死锁的产生。(In order to understand the resource allocation of the system, it is assumed that any resource of the system can only be used by one process at any one time. Any resources that have been occupied by the process can only be released by the process itself, rather than by other processes. You must wait when the resources for the process cannot be satisfied. Therefore, as long as the resource allocation algorithm can guarantee the resource request of the process, and there is no circular waiting, the system will not deadlock. Write the system scheduling procedures for resources, using bankers algorithm, effectively avoid the deadlock.)

这是一款自己独立开发的音频播放器！特此拿出来和大家共同分享！希望多多指教！(This is an independent development of their own audio player! We are here to share it with you! Hope to teach!)
