程序：全主元Gauss消去法 过程：gaussq(aa,bb,xx,n,sgn) 作用：aa为系数矩阵，bb为右端向量，xx为解向量，n为方程阶数，sgn为标识符，1表示计算正常进行，0表示计算失败 方程形式为：aa(n,n)*x(n)=bb(n)-Procedure: All the main element Gauss elimination process: gaussq (aa, bb, xx, n, sgn) Role: aa for the coefficient matrix, bb for the right-hand side vector, xx for the solution vector, n the order of the equation, sgn as identifiers, 1 indicates the calculation as normal, 0 indicates failure of the calculation equation of the form: aa (n, n)* x (n) = bb (n)

一个基于简单的LBP程序的验证程序，得到LBP图以及其直方图，通过对比直方图可以看出两幅输入图像的相似性，有LBP的三种模式：一致模式、旋转不变模式、旋转不变一致模式。

1．简介 本程序是用纯C语言编的一个基于菜单命令行的数据库系统。可以创建多个数据库，数据库表，字段。其中字段的类型只能为整形，浮点型，字符型和字符串型（最大长度确定，不能改变）。 2．功能 a)数据库存储： 一个数据库存储于一个文件中，打开文件将数据库载入到内存。 保存时将内存中数据重新写到文件中去。 b)数据库管理： 提供数据库的创建，表的创建，字段的创建 提供对数据的查询，删除，修改，排序功能 c)支持SQL部分语句： 支持SELECT 和DELETE语句-1. Introduction of this program is pure C language based on a series of menu command-line database system. You can create multiple databases, database tables, fields. The type field which can only plastic, floating point, character and string (maximum length and can not be changed). 2. A function) database storage : a database stored in a document, the document will open the database to include memory. When will preserve memory data re-wrote a document. B) database management : to provide database creation, table creation, the field for the creation of data inquiries, delete, modify, sequencing feature c) some support SQL statement : support DELETE and SELECT statements
