迭代学习程序，用迭代实现一个简单的控制，结果表明控制效果十分好(Iterative learning process in matlab，a simple case，so easy，use a short method，how i need to write，so hard！Iterative learning process in matlab，a simple case，so easy，use a short method，how i need to write，so hardIterative learning process in matlab，a simple case，so easy，use a short method，how i need to write，so hard)

倍频程和三分之一倍频程滤波器设计源代码 希望大家多多交流(Octave and third octave filter design source code hope that we can exchange)

对电磁波三维传播的仿真，包括在自由空间的传播和FDTD算法的有界空间传播(Three-dimensional simulation of electromagnetic wave propagation, including propagation in free space bounded space propagation and FDTD algorithm)

make colorbar in plot figures in matlab adjustable.

说明：  关于改进算法MLs的论文 有推导过程 可以参考(Algorithm MLs on the improvement of the paper can refer to a derivation)

matlab程序，用pca分解重构对原始信号进行噪声抑制，利用bic准则进行主分量阶数选择(matlab program, using pca decomposition and reconstruction of the original signal noise suppression, the use of principal component bic guidelines Order Selection)

Field Ⅱ超声成像代码，可以进行单个孔径成像和合成孔径成像、加权和不加权仿真。(The calculation of point spread functions is done by placing a point in front of the transducer and then sweeping the beam over the point. This gives the point spread function of the imaging system. Field II can make this calculation for a number of points simultaneously and thereby reveal the dynamic focusing properties of the imaging system. A point phantom has been made for this purpose. It consists of a number of point targets placed with a distance of 5 mm starting at 15 mm from the transducer surface)

粒子群优化寻找最适合的核函数和惩罚因子，为了更好的进行故障分类判断(Particle swarm optimization to find the most suitable kernel function and penalty factor, in order to judge the fault classification)

用matlab编写的用来求解四步相移法的光栅相位的程序(This is a matlab prepared for the four-step phase shift method to solve the grating phase program)

说明：  Matlab从入门到精通中所有的源程序。(Matlab from entry to master all of the source.)
