概念格的构造问题是形式概念分析应用的前提。由于概念格的时空复杂度随着形式背景的增大而可能指数性的增大，有关概念格的生成问题一直是形式概念分析应用研究的一个重点。国内外的学者和研究人员对此进行了深入的研究，提出了一些有效的算法来生成概念格，这些算法一般可分为两类：批生成算法(Batch Algorithm)和渐进式生成算法(Incremental Algorithm )。。 (Concept lattice structure problem is the premise formal concept analysis applications. Since the concept of space-time lattice with the increasing complexity of the form and context may increase exponentially, generating questions about the concept lattice has been a focus of formal concept analysis applied research. Domestic and foreign scholars and researchers conducted a thorough study made a number of efficient algorithms to generate the concept lattice, these algorithms can be divided into two categories: batch generation algorithm (Batch Algorithm) and progressive generation algorithm (Incremental Algorithm ). .)

数字信号处理FFT算法rfft.c，简单易懂。。(Digital signal processing FFT algorithm rfft,Straightforward..)

可以进行简单的数学运算：加、减、乘、除,sin(),cos(),tan()等，还可以对数字进行取余和开方的运算。但仅限于十进制下，还可以进行数的正、负之间的相互转换，exit表示退出, clear表示初始化，有一个 TextField用于显示传来的计算结果；Server端用于监听连接请求、计算发送过来的两数的和、送回数据结果。(Can perform simple arithmetic: add, subtract, multiply, divide, sin (), cos (), tan (), etc. can also figure to take over and prescribing arithmetic. But only under the metric system can also be used for a number of positive and negative between the conversion, exit, said exit, clear that the initialization, there is a TextField to display the results from the calculation Server client connection requests for eavesdropping, calculated sent the two and the number of returned data.)
