this code is tell about segmentation of an image

矩阵运算与优化，包括特殊矩阵的生成及稀疏矩阵的介绍(Matrix calculation and optimization, including the introduction of a special matrix generation and sparse matrix)

频谱周期图的MATLAB程序，主要对信号进行加窗处理，包括海明窗等等(Periodogram spectrum)

说明：  变论域模糊PID控制算法例程，希望多交流指教！(Variable universe fuzzy PID control algorithm routine, I hope more share advice!)

说明：  主要讲解偏微分方程组的离散方法，包括有限差分法，有限体积法(Mainly on the discrete method of partial differential equations, including finite difference method, finite volume method)

这是nmflab的操作指导书，可以当成一个工具箱添加到matlab中，其中包含nmf几种经典的算法，很有指导意义！(This is the operating instructions nmflab can be added as a toolbox to matlab, which contains nmf several classic algorithms, is very instructive!)

一个FFT改进版程序，使用kaiser窗；可以方便地打出信号的频谱包络，以及算出SNR/SINAD/THD/SFDR等各种数值。工程上使用非常便利(FFT with Kaiser Wndw, easily plot out the Frequent spetrum and the SNR/SINAD/THD/SFDR performance values)

DSCDMA的matlab实现，当下ds-cdma是基带传输的主要组成部分，该程序通过对扩频、编码的应用实现。(DSCDMA matlab realize, the moment ds-cdma is a major component baseband transmission, the program spread through the encoding application implementation.)

用MATLAB对图象进行放大或缩小,用双线性内差值方法.(zoom in or out the picture)
