two pole voltage switched PWM voltage control circuit in matlab&simulink

this program simulates 2D electromagnetic Maxwell equations , by using finite difference time domain method FDTD..and it simulates the perfect matched layer to prevent the reflections that may occure at the boundaries of the problem space

This is the collection of matlab files for recognition purposes.

BDS检验用来检测时间序列的非线性 经过测试可以用(The BDS test used to detect the time-series of nonlinear After the test can be used)

QPSK 调制解调的仿真测试，可测试误码率传信率等(QPSK test)

《自适应滤波器》教材第四章代码，很全面，对应(" Adaptive Filter" textbook Chapter IV code, very comprehensive, correspondence)

说明：  基于模数运算的数字水印算法的matlab源代码(Modular arithmetic based on digital watermarking algorithm matlab source code)

这个是详细的粒子群算法代码。大家可以借鉴参考。(This is the detailed particle swarm optimization code. We can learn from the reference.)

虽然奇异值分解（SVD）和特征值分解（EVD的）是行之有效的，可以通过先进的设施设备先进的算法，它不是通常所说，有一个内在的迹象，可以显着影响的不确定性的结论计算及诠释来自其结果。我们提供一个解决方案，标志模糊的问题确定了从奇异向量的内积和个人数据载体签署奇异向量的迹象。该数据可能有不同的载体，但它有它自身的定位和实际意义的选择方向，其中多数的向量点。这可以通过评估发现了内心的签署标志产品的总和。(Although the Singular Value Decomposition (SVD) and eigenvalue decomposition (EVD) are well-established and can be computed via state-of-the-art algorithms, it is not commonly mentioned that there is an intrinsic sign indeterminacy that can significantly impact the conclusions and interpretations drawn from their results. We provide a solution to the sign ambiguity problem by determining the sign of the singular vector from the sign of the inner product of the singular vector and the individual data vectors. The data vectors may have different orientation but it makes intuitive as well as practical sense to choose the direction in which the majority of the vectors point. This can be found by assessing the sign of the sum of the signed inner products. )

此代码为最佳阙值源程序:实现对图像的分割,是一种自动确定最佳阙值的方法,简单易行.(It can be applied into division of a certain picture,and behaves in a simple way with relatively better impact. )
