介绍了matlab中的帮助命令，比较全面，能让学习者快速取得帮助。(The introduction of the matlab help command, a more comprehensive and allow speedy access to help learners.)

绘制石墨烯结构，石墨烯为单层石墨结构，因其在性能上的优越性，引起了广泛的关注(graphene)

matlab的常用命令，对于matlab的初学者非常有用。都是关于matlab的最基本的函数命令。(matlab commonly used commands, very useful for matlab beginners. Are the most basic functions on matlab command.)

分别编写BPSK与QPSK调制解调系统的Matlab仿真程序，要求：发送滤波器与接收滤波器均为根升余弦滚降滤波器；信道噪声为加性高斯白噪声 绘制BPSK与QPSK调制下的误码率与信噪比曲线图，并与理论曲线比较对比(They were written BPSK and QPSK modulation and demodulation system Matlab simulation program requirements: a transmission filter and a reception filter are root raised cosine filter channel noise to draw error BPSK and QPSK modulation under additive white Gaussian noise rate and SNR graph, and compare and contrast the theoretical curve)

（一）在MATLAB环境下建立任意节点数n在不同通信半径r下的无线传感器网络连通图。 （二）在MATLAB环境下仿真相同通信半径、不同节点数的无线传感网络的连通率，以及相同节点数、不同通信半径下的无线传感网络的连通率。 (COMPOW Algorithm)

LS-ESPRIT算法，能够有效的测出信号的位置(LS-ESPRIT algorithm can effectively detect the location of the signal)

该文件包含spwm的单极性和双极性MATLAB smulink仿真，可以正确运行，载波与调制波波形清晰完美。由本人原创搭建。(This file contains the SPWM unipolar and bipolar MATLAB smulink simulation which can run correctly, carrier and modulation wave forms are perfect.)

这个函数返回n点2dw波段的傅里叶变换的DFT样本序列。通常情况下，以插值点的方式进行放大。(This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.)
