关于Matlab PACE workshop 的详细介绍资料，可以供大家参考(Matlab PACE Workshop of presentation materials for your reference)

说明：  EM最大期望算法：算法是在概率模型中寻找参数最大似然估计或者最大后验估计的算法，其中概率模型依赖于无法观测的隐藏变量。最大期望经常用在机器学习和计算机视觉的数据聚类领域。(EM algorithm)

这是一个医学图像重建程序，用的是滤波反投影算法。(Medical Image Reconstruction using Filtered Back Projection. Matlab code (GUI)+ 4 Sinograms for testing/demonstrations. Can be used as a laboration to compare different numbers of projections, filters and interpolation methods.)

基于MATLAB的直流调速系统仿真研究,含有对双闭环直流调速仿真的例子(Simulation of DC speed control system based on MATLAB)

This Matlab Code models a Rayleigh fading channel using a modified Jakes channel model. A modified Jakes model chooses slightly different spacings for the scatterers and scales their waveforms using Walsh–Hadamard sequences to ensure zero cross-correlation. alpha_n = frac{pi(n-0.5)}{2M} and eta_n = frac{pi n}{M}, results in the following model, usually termed the Dent model or the modified Jakes model: R(t,k) = sqrt{frac{2}{M}} sum_{n=1}^{M} A_k(n)left( cos{eta_n} + jsin{eta_n} ight)cos{left(2pi f_d t cos{alpha_n} + heta_{n} ight)}. The weighting functions A_k(n) are the kth Walsh–Hadamard sequence in n. Since these have zero cross-correlation by design, this model results in uncorrelated waveforms. The phases ,! heta_{n} are initialized randomly and have no effect on the correlation properties. Matlab fast Walsh-Hadamard transform function is used to efficiently generate samples using this model.
