自编Kalman滤波算法仿真示例程序Matlab版(Kalman filtering algorithm own procedures Matlab simulation sample version)

说明：  matlab数值编程使得数值计算工作量大大减轻，但是由于它其实是一种解释语言，而且没有国际标准，另外也没法在没有安装matlab的计算机上运行，不能用于计算密集型应用场合，极大地限制了它地应用，主要应用于物理，数学和化学，部分工程应用领域的计算工作量小的科技工作者。计算工作量大的工作，如流体力学求解，虽然matlab有解偏微分方程组的方法，但那几乎是用来作为例子来说明的，换句话说，只能作为上课例子。大型流体力学计算是计算密集型的一个例子，需要高效运算程序或并行化处理。 (chao liu ji suan)

说明：  数字信号处理中的fft算法，非自带程序，各种窗函数的编写。(Fft digital signal processing algorithms, non-native program, the preparation of a variety of window function.)

用MATLAB仿真出改进FWGN信道模型　优于普通FWGN信道模型　两者可以作比较(MATLAB simulation of improved FWGN channel model is superior to both ordinary FWGN channel model can be compared)

mathews数值分析书的源代码，用matlab编写，第一章第十六部分。(mathews numerical analysis of the book' s source code, using matlab, the first part of Chapter XVI.)

说明：  利用计算机仿真运算,将问题的求解过程转换成类似生物进化中的染色体基因的交叉、变异等过程。在求解较为复杂的组合优化问题时,相对一些常规的优化算法,通常能够较快地获得较好的优化结果。遗传算法已被人们广泛地应用于组合优化、机器学习、信号处理、自适应控制和人工生命等领域(Using computer simulation operations, the problem-solving process is transformed into a process similar to the crossover and mutation of chromosomal genes in biological evolution. When solving more complex combinatorial optimization problems, compared with some conventional optimization algorithms, better optimization results can usually be obtained faster. Genetic algorithm has been widely used in the fields of combinatorial optimization, machine learning, signal processing, adaptive control and artificial life)
