语音信号的特征提取，MATLAB编程实现LPC分析(LPC)

matlab关于有限元的一些知识，希望对大家有帮助。(Some of the finite element matlab knowledge, we want to help.)

matlab学习的相关例程，供大家学习参考，希望多多交流，共促进步，谢谢大家！(Matlab learning related routines for people to study, reference, hope more exchange, total promote steps，Thanks!)

(1) 产生数值为±1的用户随机数据；给出Matlab下对应的模块； (2) 产生并给出64×64的Walsh矩阵，作为用户接入的扩频码； (3) 利用上述一个用户的扩频码和用户数据演示扩频过程；给出Simulink工作框图； (4) 利用FFT，计算并画出基带数据和扩频信号的频谱（在一个图中给出）； ((1) value of ± 1 generated random data users given under the corresponding Matlab module (2) generation and gives the Walsh 64 × 64 matrix, as the user access to the spreading code (3) the use of the a user' s spreading code and spread spectrum user data presentation process given work Simulink block diagram (4) the use of FFT, calculate and draw the base-band spectrum data and the spread spectrum signal (given in a diagram) )

给出了(2,1,3)卷积编码和维特比译码的源程序(Given (2,1,3) convolutional coding and Viterbi decoding of the source)

说明：  matlab有关K近邻分类算法，很不错，看看(matlab knn )

实现遗传算法的基本历程，可以自由修改变异概率，交叉概率，迭代次数等(Basic Course genetic algorithm, can be freely modified mutation probability, crossover probability, the number of iterations)

说明：  这是一个基于最大信息判据的盲源分离算法程序，这个程序能很好的分离信号。(This is a criterion based on the maximum information algorithm for blind source separation procedures, which can be a very good signal separation.)

SDOF system distance calculate using Duhamel integral method。

利用图像分割检测细胞，在获得细胞的边缘后，使用形态学中的膨胀操作和填充操作使细胞边缘跟光滑。(Cells were detected by image segmentation, the edge in access to cells, use the morphology of the expansion of operations and fill with the smooth operation of the cell edge.)
