SDFT FFT算法

数值计算里经典的欧拉算法的源程序，采用matlab写的，对理解欧拉算法有很大的帮助作用。(Numerical calculation in the classical Euler algorithm source code, using matlab write, for understanding Euler algorithm has a great help.)

说明：  matlab科学计算继续上传，一共10个章节，由浅入深，几乎包括了绝大部分的科学计算方法以及仿真。本人把部分算法做了优化，更为完善(matlab scientific computing continue to upload a total of 10 chapters, easy-to-digest, almost, including most of the scientific method of calculation and simulation. I have done a part of algorithm optimization, a more perfect)

新加入条件属性对决策属性的依赖度计算函数。基于粗糙集。(The new conditions for accession to the decision attribute attribute dependency calculation functions. Based on rough sets.)

4) 创建一个名为Complex的类，进行复数的算术运算。复数的形式为： realpart+imaginarypart*i 用浮点变量表示类的private数据。提供构造函数，能够对所声明的该类对象进行初始化。在不提供初始化值的情况下，该构造函数应包含默认值。针对以下功能，分别提供一个public成员函数。 （1）两个复数相加； （2）两个复数相减 （3）用（a, b）的形式打印复数，其中a为实部，b为虚部。 (4) Create a class called Complex, and perform complex arithmetic operations. Plural form: realpart+imaginarypart* i said private data class with floating point variables. Provide a constructor, the object can be declared for the class is initialized. In the case do not provide initialization values, the constructor should contain default values. For the following functions, which provide a public member function. (A) two complex numbers (2) the subtraction of two complex (3) (a, b) in the form of plural printing, where a is the real part, b is the imaginary part.)

说明：  直接扩频序列的仿真 bpsk调制解调 有图示说明(DSSS simulation)

路径规划的几种改进的算法的仿真模拟，可直接运行，包括改进的a星人工势场等等(path planning simulation)

说明：  属于真实气体状态方程，可用于计算气体温度、压力和密度。(Calculate physical parameters of a gas, such as pressure, density, and temperature)

用于拉曼光谱的数据处理，有光谱的平滑和数据校正等代码(Data processing for Raman spectroscopy, spectral smoothing and data correction)
