基于2阶消失矩的Coifman小波基函数的2维MRTD电磁散射正演模型，吸收边界为PML。(Based on 2 vanishing moments of the Coifman wavelet function of 2-D MRTD forward model of electromagnetic scattering, absorbing boundary for the PML.)

说明：  基于非线性PCA准则的两个盲信号分离算法， 利用矩阵广义逆递推得到一种盲信号分离算法，采用梯度下降算法和线性寻优而得到另一种自适应盲信号分离算法(sourceseparation based nonlinear pca princple)

混沌系统的吸引子，很简单，初步学习可以看看(Attractor of the chaotic system is very simple, the initial learning can take a look at)

用MATLAB做SVPWM仿真分析，三电平SVPWM仿真模型(MATLAB do SVPWM simulation analysis, three-level SVPWM simulation model)

利用wavelet transform及wavelet modulus maximum來求出改良过的邊緣檢測，得到最佳的輪廓(The use of wavelet transform and the wavelet modulus maximum to derive a modified edge detection, the best contour)

matlab的维纳滤波器源码，内容较少，但滤波器的功能都有！(the source code of Wiener filter)

SIFT特征（Scale-invariant feature transform，尺度不变特征转换)是一种电脑视觉的算法用来侦测与描述影像中的局部性特征，它在空间尺度中寻找极值点，并提取出其位置、尺度、旋转不变量(SIFT features (Scale-invariant feature transform, scale-invariant feature transform) is a computer vision algorithm to detect and describe the image characteristics of the locality, it scales in space to find extreme points, and extract its location , scale, rotation invariant)

求电磁场边值，程序简洁，方法得当，运算速度快，是这一程序的最突出的特点(For electromagnetic field boundary value, the program is simple and methodologically sound, computing speed, this procedure is the most prominent feature of)
