基于Matlab的FDTD算法，很有参考价值。(Matlab based on the FDTD algorithm, a good reference.)

图像加噪和去噪代码，读取图像数据，产生噪声图像，使用sym4小波进行三层分解(Images with noise and denoising code, read the image data, image noise, the use of three wavelet decomposition sym4)

两块无线大的PEC板位于YOZ平面，一块位于x=0电位为0V，另一块位于x=4电位为20V，使用一维有限元方法求解板间电位。 (Two wireless PEC board located YOZ to plane, one at x = 0 potential is 0V, and the other one is located in x = 4 the potential of 20V, the one-dimensional finite element method for solving the potential between the plates. )

关于对embedded matlab function的使用的文档，详细说明embedded matlab function的用法(Document on the use of embedded matlab function, detailed description of the usage of the embedded matlab function)

Contrast Limited AHE (CLAHE) differs from ordinary adaptive histogram equalization in its contrast limiting. This feature can also be applied to global histogram equalization, giving rise to contrast limited histogram equalization (CLHE). In the case of CLAHE, the contrast limiting procedure has to be applied for each neighbourhood from which a transformation function is derived.

本程序是一个数据分类的程序，首先使用KL变换对数据进行降维和去噪，然后用BP神经网络对预处理过后的数据进行分类，并且留有部分的测试集(This program is a data classification program, the first to use KL transform data dimensionality reduction and de-noising, then BP neural network to classify the data after preprocessing, and left part of the test set)

三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出.以第1边界条件为例,用节点处二阶导数表示三次样条插值函数,用追赶法求解相关方程组.通过Matlab编制三次样条函数的通用程序,可直接显示各区间段三次样条函数体表达式,计算出已给点插值并显示各区间分段曲线图.(Cubic spline interpolation function from the real problems of boundary conditions cubic spline interpolation is required to give the state of the endpoint. Boundary conditions in the first example, the second derivative with node represents a cubic spline interpolation function, solving equations associated with catch-up method group. preparation of common procedures cubic spline function through Matlab, can directly display each range segment cubic spline function body expression, to the point of interpolation has been calculated and displayed for each sub-interval graphs.)
