说明：  基于测地距离不变性的非线性降维算法源码，原文发表在2000年的Science杂志上，需要了解具体原理者请先看其论文。(based on geodesic distance invariance of nonlinear reduced dimension algorithm source code, the text published in 2000 in Science magazine, the need to understand the specific tenets who can post their papers.)

本论文首先介绍了当前深空通信的编码调制技术的现状与发展，阐述了以往 的深空通信中的编码和调制技术的方案和局限性，提出LDPC码和FQPSK调制的 优越性和发展前景。第二章描绘了LDPC码的奇偶校验矩阵的图形表示、生成方 式和译码方法，并比较二元LDPC码和多元LDPC码的优越性和实现问题。第三 章在介绍FQPSK调制的方案的由来、改进和发展的基础上，对其进行了功率谱分 析，介绍了一些常规的解调方案。(This paper introduces the current situation and development of the technology of deep-space communication code modulation on the coding and modulation techniques in deep space communications program and limitations of the proposed of LDPC codes FQPSK modulation superiority and development prospects. Chapter II depicts a graphical representation of the LDPC code of the parity check matrix generation method and decoding method, and compare the superiority of binary LDPC codes and multiple LDPC code and implementation problems. Chapter origin in the introduction FQPSK modulation program, improvement and development on the basis of its power spectrum analysis, conventional demodulation.)

函数逼近的程序是一元函数的逼近，效果不错(function bijin de chengxu )

.已知某炉温控制系统，要求温度保持在600℃恒定，针对该控制系统有以下控制经验： （1）若炉温低于600℃，则升压，低的越多升压越高； （2）若炉温高于600℃，则降压，高得越多降压越低； （3）若炉温等于600℃，则保持电压不变。 设模糊控制器为一维控制器，输入语言变量为误差，输出为控制电压。输入输出变量的量化等级为7级，取5个模糊集，试设计隶属度函数误差变化划分表，控制电压变化划分表和模糊控制规则表。 (Known for a temperature control system that requires a constant temperature is maintained at 600 ℃, the following control experience for the control system: (1) If the furnace temperature is below 600 ℃, the step-up, the more the higher the lower the boost (2) if the furnace temperature is higher than 600 ℃, the blood pressure, high blood pressure, the lower the more (3) If the furnace temperature is equal to 600 ℃, then keep the voltage constant. Set of fuzzy controller for one-dimensional controller, input linguistic variables for error, the output control voltage. Input and output variables of quantization levels for seven, take five fuzzy sets, membership function test design error variance divided table, partition table and the control voltage variation fuzzy control rule table.)
