串的一些基本运算，删除一段子串，置换，求s串中从start位置开始长度为len的子串等等(Some of the basic string operations, delete a substring, replacement, seeking s string starting from the start position of the sub-string of length len, etc.)

说明：  FSK信号的解调，采用最原始底层语言编辑各模块实现(FSK signal demodulation, adopt the most primitive language editing each module implements bottom )

使用MATLAB对数字信号进行中值滤波，尤其可以对图像进行滤波处理(Use MATLAB digital signal filtering, in particular, the image can be filtered)

数字图像隐藏技术的仿真，针对一个图片现将其转换为灰白图像，然后将要隐藏的图片加入样本中，加入椒盐噪声攻击，最后将图片还原。(Digital image information hiding technology simulation, for a picture now converted to gray image, will then be hidden image is added to the sample, adding salt and pepper noise attack, finally will restore the picture.)

说明：  优化算法，寻找全局最优解，放入matlab预设目录直接可以使用(optimization algorithm)

说明：  免疫克隆算法求函数最优值，人工免疫具有分布式、自学习、自适应、自组织和鲁棒性等特点，具有强大的信息处理和问题求解能力。免疫克隆选择算法是一种受生物免疫系统克隆选择原理启发而设计的新型智能优化算法。它结合了问题的先验知识和生物免疫系统的自适应能力，因而在信息处理方面具有较强的鲁棒性，在搜索过程中能更好地收敛到全局最优解。(Immune clone algorithm to find the optimal value of function)
