An-Introduction-to-Programming-and-Numerical-Meth

说明：  在二维图像上加噪声，有加白噪声或椒盐噪声，简单小程序。仅供个人参考。如果你是刚接触matlab的请下载改程序。如果你已经接触很久matlab了，就不要下载了以免浪费你的资源分。 (Plus noise at the two-dimensional image, with added white noise or impulse noise, simple little program. For personal reference. If you are new to matlab please download the reform process. If you have access to matlab a long time, do not download so as not to waste your resources in minutes.)

matlab的追赶法，追赶法是适用于三对角矩阵的线性方程组求解的方法，并不适用于其他类型矩阵，及matlab的gauss求解方程方法，牛顿插值法，拉格朗日插值法。(matlab chasing method chasing method is applicable to the tridiagonal matrix method for solving linear equations, does not apply to other types of matrix and matlab gauss solving equations method, Newton interpolation, Lagrange interpolation.)

JEPG2000的开源代码，matlab版本可直接使用。(JEPG2000 open source code, matlab version can be used directly.)

说明：  实现小波数字水印，比较简单 采用量化数组嵌入(The realization of wavelet digital watermarking, is relatively simple to quantify the use of embedded array)

是关于空时编码的nrs ，给出了Matlab程序实现，希望有借鉴意义。 (on space-time coding nrs given Matlab program, with the hope of reference.)

分集技术，采用最大比合并的误码率性能曲线(Diversity techniques, the BER performance curve of maximum ratio combining)

说明：  Lame波的频散曲线，包括相速度和群速度。(The dispersion curve of Lame wave includes phase velocity and group velocity.)

内点法对非凸非线性规划的解法，求得最优化的解。(Interior point method for solution of non-convex nonlinear programming, to achieve optimum solution.)

说明：  一些入门的并网控制系统，含光伏和储能部分。(Some introductory networked control systems, including photovoltaic and energy storage)
