喷泉码中的LT码的程序，基于鲁棒孤波分布，有待完善(fountain code)

包络曲线的求法 matlab中的一种求上下包络的算法，特别经典的两种算法(Envelope curve for France matlab down in one envelope seeking algorithms, especially the classic two algorithms)

说明：  ieee distribution test feeder

说明：  Gauss列主元素消去法,同时给了Matlab的M文件和C代码文件。(out the main elements of Gauss elimination, but also to the Matlab M C code files and documents.)

Descriptor for simple shapes (e.g letters). Computes the descriptor twice in order to describe horizontally and vertically with the same accuracy. Input: image (2-D, binary or gray) depth of recursion (default 7), plotFlag(if on - plot Illustration) Output: vec - descriptor: Division locations, values around zero. Of length 2*(2^depth - 2) (levels: the depth of the division locations.)

用有限差分法求双脊金属加载矩形波导的基模及第一个高阶模的色散特性曲线( Finite difference method seeking double-ridged metal loaded rectangular waveguide fundamental mode and first higher order mode dispersion characteristic curve)

GA优化BP很详细的注释，而且里面加载了实际应用的例子效果很明显(GA optimization of BP very detailed notes, and which examples of practical application loading effect is obvious)

其主要特点是直接对结构对象进行操作，不存在求导和函数连续性的限定；具有内在的隐并行性和更好的全局寻优能力；采用概率化的寻优方法，能自动获取和指导优化的搜索空间，自适应地调整搜索方向，不需要确定的规则。( Its main feature carries on the operation directly to the structure object, does not have the derivation and the function continuous definition Has the intrinsic hidden parallelism and better overall situation optimization ability Uses the randomization the optimization method, can gain the search space which automatically and the instruction optimizes, adjusts the search direction auto-adapted, does not need to determine rule. )
