费诺编码的步骤: A 将概率按从大到小的顺序排列 B 按编码进制数将概率分组，使每组概率和尽可能接近或相等。 C 给每组分配一位码元 D 将每一分组再按同样原则划分，重复b和c，直到概率不再可分为止

The package contains a Reed-Solomon coding and decoding program, derived partly from Phil Karn/Robert Morelos-Zaragoza "new_rs_erasures.c". In particular the Berlekamp-Massey algorithm has not been modified. New features compared to "new_rs_erasures.c" are: - fully parameterized: code parameters ...

AppWizard has created a WCEDialogWiz DLL for you. This DLL is the starting point for writing your custom AppWizard. It demonstrates the basics of creating a custom AppWizard.

This sample provides a generic example of a PCI IDE minidriver. The sample isolates vendor-specific code from the higher-level PCI IDE bus driver, much as SCSI minidrivers isolate code from the SCSI port driver. See the Release Notes section for more information. This sample works on both x86 and A ...

按照Clifford A . Shaffer《数据结构与算法分析（第二版）》指导，用C#实现的B+树，接口定义良好。最好重写“从文件载入新建树部分”的代码以提高建树效率。实现细节之一：当“需要插入子节点的节点”已满而相邻节点未满时会平分两者节点而不是分裂该节点。 ...

libsvm is a simple, easy-to-use, and efficient software for SVM classification and regression. It solves C-SVM classification, nu-SVM classification, one-class-SVM, epsilon-SVM regression, and nu-SVM regression. It also provides an automatic model selection tool for C-SVM classification. This docume ...
