数学频谱分析仪,主要是对于频谱的分析，能够有图显示。(Mathematical spectrum analyzer, such as the title, in the inside the mathematical spectrum analyzer, such as title, inside.)

这是用龙贝格求解数值积分的一种方法，精确性高(This is solved using Romberg numerical integration method, high accuracy)

XFEM扩展有限元模拟二维裂纹动态扩展，由哈弗大学一个研究小组开发，非常值得学习(XFEM extended finite element simulations of two-dimensional crack dynamic propagation, developed by a team at Harvard University, is worth learning)

clear 从内存中清除变量和函数 exit 关闭MATLAB load 从磁盘中调入数据变量 pack 合并工作内存中的碎块 quit 退出MATLAB save 把内存变量存入磁盘 who 列出工作内存中的变量名 whos 列出工作内存中的变量细节 workspace 工作内存浏览器 (There is one outlier in the data of , but is not of data .For and the line of Q2 is in the middle of the box, so there are not asymmetries for both and .)

基于蒙特卡罗法2PSK系统抗噪声性能仿真 编写MATLAB的M文件，用该文件的采用相干解调法的2PSK系统的抗噪性能进行1000个符号的蒙特卡罗法仿真，画出误码率与信噪比之间的关系曲线(Based on the Monte Carlo simulation of anti noise performance of 2PSK system Write a MATLAB M file, the file by using the coherent demodulation method for 2PSK system anti-noise performance of 1000 symbols of the Monte Carlo simulation, draw the error rate and signal to noise ratio and the relation curve between the )

Monte Carlo检验程序，用以检验生物与环境因子相关系数。在生态学上应用较广(Monte Carlo)

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is a space-time block coding based on the MIMO_OFDM communication system simulation design. This system consists of QPSK modulation and demodulation, IFFT modulation, space-time coding and decoding, based on training symbols such as communication channel estimation module.)

说明：  一个很有用的PID控制程序，用于性能评价，主要是看仿真图的(A useful PID control procedures for performance evaluation, mainly the simulation map)
