计算一维和二维卷积,基本可以替代Matlab中的conv和conv2函数,程序很方便就可以移植成C语言..(Calculation of one-dimensional and two-dimensional convolution, the basic alternative to Matlab' s conv and conv2 function, the procedure can be easily transplanted into a C language ..)

一些matlab底下的小函数，详细见索引。直接解压，不用密码。(under Matlab some small function, see detailed index. Direct unpack, without a password.)

带通滤波，对输入的数据进行带通滤波，采样频率为实际频率的16倍，里面有关于矩阵和数据变换的程序，大家可以自己转换(Band-pass filter, the data input bandpass filter, the sampling frequency is 16 times the actual frequency, which on the matrix and data transformation process, we can convert their own)

说明：  是一种关于无线传感器网络的质心定位程序的MATLAB原代码.希望对大家有帮助...(Is a wireless sensor network on the centroid position of the MATLAB program source code. I hope all of you help ...)

QPSK信号通过瑞利衰落信道后的误比特率和误符号率，并与AWGN信道下的误比特率和误符号率进行对比。其中，多普勒频移为 100Hz，经过矩形脉冲成形后的抽样时间间隔为1/800000s。(The QPSK signal harms the bit rate after the Rayleigh fading channel and harms the mark rate, and harms the bit rate with the AWGN channel under and harms the mark rate to carry on the contrast. And, the Doppler shift is 100Hz, after undergoing the square pulse forming the sampling time gap is 1/800000s. )

绘制不同情况下的升余弦滚降系统频谱，并画出其各自对应的时域波形(Draw different circumstances raised cosine roll-off system spectrum, and draw their own corresponding time-domain waveform)

线性代数实践及MATLAB入门 本书是根据“用软件工具推向线性代数教学”的指导思想，参照美国1992-1997国家科学基金项目ATLAST的思路，编写成的线性代数补充教材，其目的是补充我国现有教材的的缺陷。它分为两篇，第一篇介绍线件代数所用的软件工具MATLAB语言，第二篇介绍线性代数实践。本书可作为大学本科线性代数的配套教材，也可作为广大理工、经管领域教师、工程师和研究生的参考读物。(Introduction to Linear Algebra practice and matlab This book is based on the guiding ideology"use of software tools into the teaching of linear algebra," , with reference to the ATLAST ideas of U.S. National Science Foundation(1992-1997) , written as a linear algebra supplementary materials, the purpose is to supplement our existing materials defects. It is divided into two parts, the first introduces line of pieces of software tools used in algebraic MATLAB, the second introduces linear algebra practice. )
