matlab用户图形界面用法的一个小例子。用到了文本框、滚动条等控件，对刚开始学习matlab有一定的帮助。(matlab graphical user interface uses a small example. Used in the text boxes, scroll bars, and other controls, just started learning matlab have some help.)

各种方程的解法，包括代数方程，线性方程组，线性微分方程等等。。(Solution of various equations, including algebraic equations, linear equations, linear differential equations and so on. .)

线性规划 包括单纯形法，梯度，牛顿(linear programming including the simplex method, gradient, Newton, etc.)

说明：  计算HURST指数，自己编写，这是经过修正之后通过变成得出来的结果，网上一般很少有这类文件。(HURST index calculation, write your own, which is revised after the results come through into a very, very few of these files online usually.)

least significant bit insertion is done using matlab..data is hidden in the least significant bit of carrier file.

Ant Colony Optimization (ACO) is a paradigm for designing metaheuristic algorithms for combinatorial optimization problems. The first algorithm which can be classified within this framework was presented in 1991 [21, 13] and, since then, many diverse variants of the basic principle have been reported in the literature. The essential trait of ACO algorithms is the combination of a priori information about the structure of a promising solution with a posteriori information about the structure of previously obtained good solutions.
