说明：  很重要的分形维二维算法是基于matlab下的配合调用matlab使用这种算法可以提高matlab的运算效率。(the code base on the matlab and it will do well in image with matlab if you use it you will find good way to identify the picture of finger)

IS95 FIR滤波器低通滤波白噪声(由输入和输出噪声功率谱图可见，IS-95滤波器较好实现了低通滤波。)(IS95 FIR low-pass filter white noise filter)

粒子群优化是一种新兴的基于群体智能的启发式全局搜索算法，粒子群优化算法通过粒子间的竞争和协作以实现在复杂搜索空间中寻找全局最优点。(Particle swarm optimization is a new global search heuristic algorithm based on swarm intelligence, particle swarm optimization algorithm by particle competition and collaboration to achieve to find the global optimum in a complex search space.)

基于matlab simulink的spwm仿真模型，非常适合初学者学习正弦脉宽调制方法使用。(The spwm matlab simulink simulation model is very suitable for beginners to learn sinusoidal pulse width modulation method.)

对光学系统中常用的正弦振幅型透射光栅进行了仿真，仿真结果有衍射图案和光强沿x轴方向的曲线。(Of the optical system used in the amplitude of the sinusoidal transmission grating-based simulation, simulation results diffraction patterns and light intensity along the x-axis direction of the curve.)

Matlab中没有现成的Hermite插值函数，必须编写一个M文件实现插值。 设n个节点的数据以数组x0 （已知点的横坐标）， y0（函数值）， y1（导数值）输入（注意Matlat的数组下标从1开始）， m个插值点以数组x 输入，输出数组y 为m 个插值。编写一个名为hermite.m的M文件。 (Matlab is not off-the-shelf Hermite interpolation function, we must realize the preparation of a document M interpolation. N nodes for the data to an array x0 (known point of abscissa), y0 (function value), y1 (numerical derivative) input (note the subscript Matlat array starting at 1), m to the array of interpolation points x input and output array y for m months interpolation. Hermite.m the preparation of a M-file.)

说明：  带约束算子的粒子群算法，用于matlab环境，对于搞研究的教师有很大帮助(Operator Constrained Particle Swarm Optimization for the matlab environment, engage in research for teachers are very helpful.)
