MATLAB 线性方程组的数值解法.part5

说明：  x=2*sin(4*pi*t)+5*cos(8*pi*t) 对其进行快速傅立叶变换 加入高斯噪声 再进行频谱分析(x = 2* sin (4* pi* t) 5* cos (8* pi* t) makes its rapid Fourier transform to re-Gaussian noise spectral analysis)

MATLAB编写的利用u律函数实现的抑制OFDM峰均比的程序，程序通过运行，通过u率函数对信号压扩后，PAR明显降低(U law written by MATLAB functions for OFDM PAPR suppression program, the program by running through the u signal compression and expansion rate after the function, PAR was significantly lower)

该书基于matlab编程来实现阵列天线方向图的形成(The book based on the matlab programming to achieve the formation of array antenna pattern)

使用matlab生成SOS滤波器，应用于FPGA的一个小型系统，有一定的参考价值(Using MATLAB to generate SOS filter, applied to a small system of FPGA, there is a certain reference value)

ASk调制与解调(MATLAB) 可以在MATLAB上直接运行(ASk modulation and demodulation (MATLAB) can directly run MATLAB)

粒子群算法用matlab实现。。实现一个函数优化(Particle swarm optimization with matlab. . The realization of a function optimization)

此程序是应用四阶龙哥库塔公式来解方程的程序。(The program is the application of fourth order longge coulthard formula to solve the equation program. )

The goals of this tool is to manipulate the fast marching algorithm in 2D and 3D. Application to shortest path extraction (e.g. road tracking and tubular structure extraction in medical images), shape statistics and geodesic remeshing are presented.(The goals of this tool is to manipulate the fast marching algorithm in 2D and 3D.

Matlab数字信号处理工具箱 MATLAB已带有数字信号处理工具箱，但不少数字信号处理学者又发展出一些数字信号处理的函数，例如我们会常用到ideal_lp、Hr_type1、dft、idft、Circonvt、freqz_m，...等等，《数字信号处理---使用MATLAB》一书提供了这样的工具箱，内容如附图，工具箱在附件中。(Digital Signal Processing Toolbox Matlab)
