此是MATLAB7.0程序设计的那本书的源代码，希望对大家能有所帮助。(This book MATLAB7.0 programming source code, I hope that we can help.)

说明：  输入圆的半径求周长和面积。程序由三个函数组成：主函数进行输入输出和函数调用，perimeter函数求周长，area函数求面积。(Enter the radius of the circle circumference and area requirements. Program consists of three functions: the main input and output functions and function calls, perimeter function evaluation perimeter, area function for the area.)

离散傅立叶变换已成为数字信号处理的重要工具，然而，它的计算量较大，运算时间长，在某种程度上却限制了它的使用范围。快速算法大大提高了运算速度，在某些应用场合已能作到实时处理，并且开始应用于控制系统。(Discrete Fourier Transform digital signal processing has become an important tool, however, the calculation of its larger, long computing time, but in a way limits the scope of its use. Fast Algorithm for greatly enhanced speed of operation, in some applications has been able to do real-time processing and control system began to be used.)

说明：  倒立摆的控制，采用常用的PID算法，现在没有加其他的算法，或许对一些同学有用。(Inverted pendulum control, with common PID algorithm, the algorithm is not added to the other, may be useful for some students.)

VC++与Matlab混合编程的快速实现(code for vc and matlab)

介绍MATLAB中灰度共生矩阵的文档，刚入门的可以拿去看看！(Documents introduced in MATLAB GLCM, just getting started can take it and see!)

用matlab语言编写的二维卷积实现代码，自创代码并在软件中实现了。(Two-dimensional convolution code written in matlab language, and create the code and is realized in software.)

pdf文档，机载雷达坐标系变换相关内容，介绍了机载雷达坐标系下的探测目标位置表达方式(pdf document，introduce the coordinates translates method of the airplane between the target)

例4：在sinc(t)信号中叠加噪声，分析对应频谱 fs=100 采样频率,必须大于两倍基带信号最高频率 ts=1/fs 采样时间间隔 T=2 时间窗大小 ( x=x+0.1*randn(1,N) x=awgn(x,-10, measured ) figure plot(t,x) title( 时域信号图 ) xlabel( t /s ) y=fft(x,N) figure if mod(N,2)~=0 N=N-1 end f=linspace(0,fs/2,N/2) plot(f,abs(y(1:N/2))*2/N) title( 叠加噪声的sinc(t)信号频谱 ) xlabel( f /Hz ) figure y0=y(1:N/2) P=y0.*conj(y0)/N P=10*log10(P) plot(f,P) title( 功率谱 ) xlabel( f /Hz ) )

matlab调用C++程序，实现for循环加速。有详细步骤，供同学参考~谢谢！(call C++ matlab program to achieve for loop acceleration. There are detailed steps for students to reference ~ Thank you!)
