说明：  闭环控制系统输入信号为阶跃信号，受控对象的传递函数为3 2 1 ( ) 2 5 s G s S s s      。(Closed loop control system for the step input signal, the transfer function of the controlled object 3 2 1 () 2 5 s G s S ss      .)

这是用matlab编写的一个源程序，希望对大家有用，不足之处还请大家谅解(This is a source code written in matlab, want to be useful, the inadequacies also please understand)

very useful matlab SVM algorithm for data mining..............

图像频域滤波，用matlab实现了在图像频域中通过Butterworth陷波器消除周期性噪声干扰信号。(Image frequency domain filtering using matlab achieved in the frequency domain image by Butterworth notch filter to eliminate periodic noise signal.)

Return matrix of all possible k indexes, it is C(n,k) variants

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

机械优化设计主要包括建立优化设计问题的数学模型和选择合适的优化方法及程序两方面的内容.基于二次插值法的基本原理,通过实例,编写MATLAB程序进行求解,计算结果说明了二次插值法是一种求解一元函数极小点问题最优解的可行高效的方法.(Mechanical optimization design includes a mathematical model to optimize the design of the problem and choose the appropriate two aspects of optimization methods and procedures based on the basic principles of quadratic interpolation method, is solved by way of example, the preparation of MATLAB, the results illustrate the quadratic interpolation method is a function of one yuan to solve the problem of the optimal solution of the minimum point efficient way possible.)
