mmread reads virtually any media file. If Windows Media Play can play it, so should mmread. It uses the Window s DirectX infrastructure to ％ render the media, so other OSs are out of luck.(mmread reads virtually any media file. If W for Windows Media Player can play it. so should mmread. It uses the DirectX in Window s GE% to render the media, so other OSs are out of luck.)

PMSM的矢量控制，坐标变化，三闭环，控制效果良好，波形不错(PMSM vector control, coordinate changes, three closed loop)

本程序是采用先进的网络结构Elman网，对糖厂PH值澄清工段进行建模。(This procedure is the use of advanced network Elman network, the PH value to clarify the Section of sugar to model.)

说明：  对语音进行解调，用MATLAB实现，希望对大家有用(For demodulation of the voice, using MATLAB to achieve, in the hope that useful)

matlab下对图像进行fft变换，平滑，锐化，中心化傅立叶正变换得到大正方形，小正方形，斜正方形。对其频谱进行中心化处理。图像的平滑和锐化，利用拉普拉斯算子。(Matlab right image fft transform, smoothing, sharpening, is the center of the Fourier transform large square, small square, ramp square. Its spectrum treatment center. Image sharpening and smoothing, using Laplace operator.)

基于高斯混合模型(GMM)的em算法，给出了其matlab实现(em algorithm for GMM)

传播算子DOA估计，DOA估计中一种分辨率比较高的算法(Propagator, DOA estimation algorithm in a resolution DOA Estimation)

用于处理迭代软门限中出现阻塞的程序。输入原矩阵和向量即可得出阻塞变量位置和解决阻塞后的矩阵。(For processing procedures of a block in the iterative soft threshold. Enter the original matrix and vector can be derived the blocking variable position and resolve the blocking matrix.)

说明：  它主要研究的是多因变量对多自变量的回归建模，特别当各变量内部高度线性相关时，用偏最小二乘回归法更有效。另外，偏最小二乘回归较好地解决了样本个数少于变量个数等问题。 偏最小二乘法是集主成分分析、典型相关分析和多元线性回归分析3种分析方法的优点于一身。它与主成分分析法都试图提取出反映数据变异的最大信息，但主成分分析法只考虑一个自变量矩阵，而偏最小二乘法还有一个“响应”矩阵，因此具有预测功能。(It is mainly a result of the study is a multi-variable regression modeling and more independent variables, especially when the internal height of each variable linear correlation, partial least squares regression method is more effective. In addition, partial least squares regression solves the number of samples is less than the number of variables and other issues. Partial least squares method is a set of principal component analysis, canonical correlation analysis and multiple linear regression analysis of the advantages of the three methods in one. It is the principal component analysis are trying to extract the maximum information reflects data variability, but the principal component analysis considers only one independent variable matrix, and partial least squares and a &quot response&quot matrix, predictive capabilities.)

实现脉冲压缩与相控阵的matlab实现 脉冲压缩雷达发射宽脉冲信号，接收和处理回波后输出窄脉冲的雷达。为获得脉冲压缩的效果，发射的宽脉冲采取编码形式，并在接收机中经过匹配滤波器的处理。脉冲压缩雷达的优点是能获得大的作用距离和具有很高的距离分辨力。(pulse compression&phased array)
