读取文件夹下的所有txt文件；功率谱变换(read data from all*.txt files in a folder Power spectral transform)

FDTD仿真，空气和玻璃界面的折射现象，可以观察到电磁波的折射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor. )

matlab 图像处理源代码，比较全，有多个matlab程序(matlab image processing source code, compare the whole, there are several matlab programs)

Gaussian distribution model

对声音信号的时域分析频域分析采样并显示时域分析结果，还有录音并显示(Time-domain analysis of the sound signal frequency domain analysis of the sample and displays the time domain analysis, as well as recording and display)

SVD-TLS算法进行参数估计，本文用SVD-TLS算法估计观测信号的功率谱，步骤如下： （1） 计算样本相关函数矩阵R的SVD，并存储奇异值和矩阵V （2） 确定R的有效秩，本文使用的是归一化奇异值法来求有效秩 （3） 用总体最小二乘法估计参数 (SVD-TLS algorithm for parameter estimation, this paper observed SVD-TLS algorithm estimates the signal power spectrum, the following steps: (1) Calculate the sample correlation function matrix R, SVD, and store singular values and matrix V (2) to determine R, effective rank, this is normalized using the singular value method to be effective rank (3) The total least squares method to estimate the parameters)

基于内容的图像检索matlab小程序，使用图像的9种主要颜色为检索特征。(content-based image retrieval Matlab small, the use of images of the nine main colors for the retrieval features.)

以上代码是求解椭圆微分算子的特征值问题的Matlab源代码，采用有限元法的思想来编写的，程序计算结果和理论是相符的。(The above code is to solve the elliptic differential operator eigenvalue problem of the Matlab source code, using the finite element method to write the ideas, procedures, results and theoretical calculation is consistent.)
