说明：  DSP中两个信号阵列卷积的两种算法。一种是看两个信号得结果，另一种是看结果的每一部分由信号中哪些部分组成。(DSP array convolution of two signals of the two algorithms.)

关于非线性光纤环形镜透射率的计算，用于光纤激光器和光纤传感器的设计和研发(Nonlinear optical fiber loop mirror)

说明：  这是个滤波器设计程序编码，希望各位朋友看看！(滤波器设计)

in this package are the programs needed to solve any problems differential linear boundary value.

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

利用matlab simulink 进行电力系统的潮流计算，很实用(Matlab simulink power system load flow calculation, it is practical)

Dufing方程是一种重要的动力系统山，是反映工程物理系统中非线性现象和混沌动力学行为的极其重要的方程式。通过Duffing方程可以探讨铁磁谐振电路中的分岔、拟周期运动、子谐波振荡。而在非线性与混沌系统的研究中，Duffing方程展示了丰富的混沌动力学行为。本文通过对不同情况下的Duffing方程进行分析，利用MATLAB进行仿真，从而对Duffing方程有进一步的了解。(Dufing equation is an important dynamic system mountain, which reflects the nonlinear phenomena and chaotic dynamics in Engineering Physics system. The bifurcation, quasi periodic motion and sub harmonic oscillation in ferromagnetic resonance circuit can be discussed through the Duffing equation. In the study of nonlinear and chaotic systems, the Duffing equation shows abundant chaotic dynamical behavior. In this paper, the Duffing equation under different conditions is analyzed and simulated with MATLAB, so as to have a further understanding of the Duffing equation.)
