采用matlab求解矩阵的逆.本程序采用完全的c语言格式在matlab平台下编制(Using matlab to solve the inverse matrix. This procedure completely the c language format in the preparation of matlab platform)

根据matlab的bvp4c函数的例子思想方法，求解特征值和特征函数，可以解变积分边界的问题，但是须给一个比较精确的初特征值。此为自编程序，已经标明注释。所附为bvp4c相关例子（此从matlab帮助文件节选）。(use the matlab solver bvp4c to obtain the both eigenvalues and eigenfunctions of BVPs, an exact initial eigenvalue is needed.)

Running a function on several files in Matlab

差分格式编码，用matlab仿真，结果可以仿出来，有需要的就下吧(Differential encoding format, with the matlab simulation, results can fake it, need it for the next)

非线性结构力学分析的matlab源程序non-linear ansis for structure(non-linear ansis for structure)

简单的一段小程序 有关于图像识别技术的 (Simply a small program on the image recognition technology)

本程序将时域数据转换为频域（功率谱密度），方便数据的处理和分析。(The program time-domain data is converted to the frequency domain (power spectral density), to facilitate the processing and analysis of data.)

matlab与C的混编，处理乘性噪声，建立M次开根号模型，需要调整参数。(written with matlab and C by S. Yun and H. Woo, "A new multiplicative denoising variational model based on m-th root transformation".)

用MATLAB实现SAPSO、SecPSO、SecVibratPSO算法，程序没错误，可以直接运行，非常适合刚学PSO者(Implementation of SAPSO, SecPSO, SecVibratPSO algorithm with MATLAB, the program no error, can be directly run, very suitable for just learning PSO )

this source code based on steganography and developed in matlab. in steganography we can hide any data like images in another image. this method based on discrite fourier transform method.
