Electromagnetic theory and applications to Photonic crystals. Advances in photonic crystals. Different methods of analysis and design of photonic crystals.

This function is intended as the "main" program. That is, execution will begin with this function it will receive commandline input from the user and return results to the user.

基于MATLAB自编kpca和pca源程序，内附运行数据，多次运行无误。谢谢(Based on MATLAB and self kpca pca source, containing operating data, multiple runs correctly. Thank you)

某型飞机机翼在风洞中测得的翼型自噪声数据，可用于多输入单输出的神经网络建模。(A certain type of aircraft wings in the wind tunnel measured airfoil self-noise data, can be used for multi-input single-output neural network modeling.)

质点外弹道，最最最基本的外弹道程序啊，不要错过啊(zhidian wai dandao,no cuoguo)

guass迭代法，是数值分析中很重要的一种，源码为其在matlab中的实现。 (guass iterative method, numerical analysis is a very important one in the matlab source code for its realization.)

this is a well data number 1 for RPH sample, stored in las format

This M Code simulate the effects of clipping and filtering on PAPR PAPR reduction in OFDM-based wireless standard.Also the performance of BER versus SNR of original OFDM signals with PAPR reduction based on clipping and filtering schemes over AWGN channel is evaluated. The simplest and most widely used technique of PAPR reduction is to basically clip the part of signals that are outside the allowed region.Clipping methode introduces both in band distortion and out of band radiation into OFDM signals which degrades the performance including the BER and spectral efficiency.Filtering can reduce out of band radiation after clipping although it can not reduce in-band radiation distortion.However, clipping may cause some peak regrowth so that the signal after clipping and filtering will exceed the clipping level at some point.To reduce peak regrowth a repeated filtering and clipping operation can be used to obtain a desirable PAPR at a cost of computational complexity increase.
