在matlab中，实现图像旋转（两种方法：临近法、双线性法）(In matlab, the realization of image rotation (two methods: near the bilinear method))

自动控制理论中利用matlab编写二阶系统分别在欠阻尼，临界阻尼，过阻尼时的情况(Automatic control theory using matlab write second-order system in underdamped, critically damped, overdamped)

主要时STTC，的编码时我再网络上收及的(sttc )

数字水印matlab程序，只是简单的svd跟最简单的置乱方法Arnold的应用。没有用到小波算法。上传的dwt_svd_GUI.rar是完整的数字水印算法，用的是混沌加密。(Matlab digital watermarking process, with the svd simply the easiest way to Arnold scrambling applications. Wavelet algorithm is not used. From the dwt_svd_GUI.rar is a complete digital watermarking algorithm, using a chaotic encryption.)

通过对基4快速傅里叶的介绍，使用matlab实现了基4快速傅里叶变化(Through the radix-4 Fast Fourier presentation, using matlab to achieve a base four fast Fourier transform)

matlab多年收集结果，包括程序和pdf介绍。(Matlab realized bootstrap source. )

一个很好的matlab编程绘制B样条曲线，(Matlab program to draw a good B-spline curve,)

基于matlab/SIMULINK仿真,对开发环境和相关内容进行了介绍(Based on matlab/SIMULINK simulation, the development environment are described and related content)

MATLAB学习书籍，感觉很不错 ，看看大家有什么需要的 ，可以下载 。(MATLAB learning books, I feel very good, to see if we need anything, you can download.)

小波包能量代码，利用db1小波将信号分解和重构，然后计算小波系数的平方，进行正则化(Wavelet packet energy code, the use db1 wavelet signal decomposition and reconstruction, and then calculate the square of wavelet coefficients, the regularization)
