关于MATLAB的工程应用基础的幻灯片，希望对大家有所帮助(matlab-based engineering applications)

EM algorithm for Gaussian mixture

说明：  程序清单A中收录了产生PPM-TH和PAM-DS这两个信号源的所有函数；程序清单B中收录了加性高斯白噪声（AWGN）信道建模，正交和非正交单脉冲PPM-TH接收机结构，以及反极性PAM-DS单脉冲接收机结构仿真所需的所有函数。(A list of procedures resulting in a collection of PPM-TH and PAM-DS these two signal sources all function procedure includes a list of B in the additive white Gaussian noise (AWGN) channel modeling, orthogonal and non-orthogonal single pulse PPM-TH receiver structure, as well as the anti-polarity PAM-DS monopulse receiver structure simulation all the necessary functions.)

稳定性求解绘制稳定性lobe图（全离散）(Stability Solving draw stability lobe diagram (fully discrete))

实现大点数的IFFT变换，先进行小点数IFFT变化，然后再进行过采样滤波，有频谱图及例子(Achieve great points IFFT transform, first have a small point IFFT change, and then over-sampling filter, a spectrum and examples)

Post processing analysis of an audio file. Digital filters and other algorithm filters not conventional.

说明：  先用.txt文件导出杆系结构和梁系结构的用于节点校核的数据，然后用matlab程序计算即可进行构件验算(time. Txt file is derived bar structure and the structure of the beam system for checking the data node, then Matlab can be calculated for checking Component)

改进的等维新息灰色模型，还有残差数列检验，后验差检验，模型精确好用。(Improved Innovation Gray Model，There are residual series test, posterior difference test, model accuracy easy to use. )

surface chart Based on particle swarm optimization画图法(surface chart Based on particle swarm optimization)

说明：  kmeans程序，用以各种方面聚类分析，诸如入侵检测和图像等。(kmeans method，used in many fields， such as intrusion detection, imag segmentation and etc. )
