生成多点地震动，多点激励，地震动的空间变异性。(spatial variation of earthquake ground motion，non-uniform excitation。)

Estimating VAR(p) processes_Matlab code

基于dictionary learning的MR图像重建的代码，希望对从事MR图像重建的朋友有用，使用matlab开的的代码～～(dictionary learning for MR image construction)

Digital signal processing(Digital signal processing program contains a variety of signal processing algorithms)

Binary erosion and dilation, with fast iterative calls. For any structuring element other than square or disk this function is way faster than imerode.m and imdilate.m (more than an order of magnitude). It s also handy when you don t have the Matlab Image Processing Toolbox :-)... It also allows very fast iterative calls (for instance when sweeping the structuring element while looking for a certain effect, threshold in image statistics, etc). See the help in bmorph.m and the attached .pdf file.

provide various conversion method used in handling android resources.

Copyed from a Phd paper：This program calculates the reflectivity of a DBR stack。

说明：  计算节点功率的失配量，方法简单，便于理解。(Mismatch calculated the amount of power nodes, the method is simple, easy to understand.)

四种高斯滤波算法的比较：EKF、UKF、QKF和CKF(Comparison of four Gaussian filtering algorithm: EKF, UKF, QKF and CKF)

it is for macrowawe and antenna that is very good
