MPSO

MATLAB Simulink Simulation Platform for Photonic Transmission Systems

计算声子晶体固-液和固-气体系，和实验测试吻合，很适应(Suitable for computing phononic crystal solid-liquid and solid and gas, and experimental agreement )

一篇关于qkf文献, 量测方程四元素线性推导过程。 (A Novel Quaternion Kalman Filter)

说明：  一维波动方程的间断有限元计算，包括网格的划分，数值积分的计算等。(Discontinuous finite element method for one-dimensional wave equation, including mesh division, numerical integration calculation and so on.)

求解声学问题的边界元程序，给声学研究的人员很大启发(Solving the problem of acoustic boundary element program, to inspire great acoustic research staff)

上三角或下三角矩阵也有大部份的元素不储存值（为0），我们可以将它们使用一维阵列来储存以节省储存空间，而对称矩阵因为对称于对角线，所以可以视为上三角或下三角矩阵来储存。(Upper or lower triangular matrix or a large majority of elements are not stored value (0), we can use them to store a one-dimensional array in order to save storage space, and because the symmetrical diagonal symmetric matrix, it can be regarded as the or lower triangular matrix storage.)

说明：  模拟退火算法，地球物理反演，非线性反演算法(Simulated annealing algorithm)

数值分析计算课程的部分习题答案，有matlab编程，希望对大家有用。(some small matlab codes .)

说明：  虽然现在网上的FFT程序很多，但是有的结果是错误的，比如说，经过一次正反变换后，不能得到原来的数列，所以，本人测试了多个程序，提供几个能用的，给大家，希望大家支持！ (Although many online FFT program, but some results are wrong, for example, through a positive and negative change, you can not get the original series, so I tested several programs to provide a few usable for everyone I hope we can support!)
