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

最小曲率扩边源代码，用于空白点补空，当在位场数据进行时域与频域转化时，离散数据必须为2的整数次幂，此时可对采集数据体利用最小曲率方法进行扩边，该算法精度较高，由于余弦扩边算法。

A Kalman filter is a stochastic , recursive estimator , which estimates the state of a system based on the knowledge of the system input, the measurement of the system output, and a model of the relation between input and output.
