蚁群算法的matlab源代码实现，十分实用。

数字带通滤波器的设计过程。共3个源程序。其中，dos.cpp为带通FIR的源程序，其中的滤波器阶数n，滤波器的低频fln，滤波器的高频fhn，窗函数w，可以按照自己的要求改变。这里采用的是汉宁窗。主函数main.cpp实现输入与fir的h(n)的卷积，输出结果Y(n)，并将其存储在y.txt中。最后，graphics.cpp从y.txt读取数据，再由语句画出波形，可以清楚地看出计算结果是否正确，并进行比较。-digital band-pass filter design process. A total of three sources. Among them, dos.cpp FIR bandpass to the source, the filter order n, the low-frequency filter FLN, the high-frequency filter fhn, window function w, in accordance with the requirements change. Here is the Hanning window. The main function main.cpp achieve the input and fir h (n) convolution, the output Y (n), and store them in y.txt China. Finally, graphics.cpp y.txt read data from and then draw waveform statement, we can clearly see whether calculations are correct, and comparisons.

稀疏算法对图像去噪， 由于在K-SVD算法中用到了OMP算法和奇异值分解SVD算法，而当图像较大时，OMP算法中的矩阵求伪逆运算效率非常低、奇异值分解SVD不仅耗时而且占用内存较大，常导致“超出内存”问题。针对上述问题本课题提出了基于矩阵shelesky分解和近似奇异值分解SVD的稀疏K-SVD噪声抑制方法来对自然图像进行噪声抑制，同时在字典训练过程中结合了“全局训练字典”的普适性，该方法有效的提高了K-SVD算法的运行效率、解决了“超出内存”问题，并且提高了去噪效果。

         瑞士的计算机学者Niklaus Wirth在1976年出版了一本书，书名为《算法+数据结构 = 程序设计》，它正说明了数据结构与算法在程序设计中的作用。程序设计的实质即为计算机处理问题编制一组

k-means 算法的工作过程说明如下：首先从n个数据对象任意选择 k 个对象作为初始聚类中心；而对于所剩下其它对象，则根据它们与这些聚类中心的相似度（距离），分别将它们分配给与其最相似的（聚类中心所代表的）聚类；然后再计算每个所获新聚类的聚类中心（该聚类中所有对象的均值）；不断重复这一过程直到标准测度函数开始收敛为止。-k-means algorithm process as follows: First of all, the object data from the n choose k object as initial cluster centers and the remaining for the other object, then according to their cluster center with those of the similarity (distance) respectively assigned to them with the most similar (represented by cluster center) clustering obtained and then calculated for each new cluster center clustering (all objects in the cluster mean) repeated this process until the standard measure of function until the beginning of convergence.
