说明：  Ofdm-UWB的仿真模型图，适合7.0的版本，包含整个协议规定的系统，可以设置FFT的点数。(Ofdm-UWB simulation model map for the 7.0 version of the agreement include the entire system can be set FFT points.)

快速傅里叶变换 (FFT) 实现，给定信号x(t)=sin(2πf0t)，f0=50Hz，对x(t)以fs=200Hz进行抽样，抽样点数为N=16。编写程序实现对x(n)的快速傅里叶变换，求得相应的X(K)。(Fast Fourier Transform (FFT) to achieve a given signal x (t) = sin (2πf0t), f0 = 50Hz, for x (t) with fs = 200Hz sampling, the sampling points is N = 16. Procedures for the preparation of x (n) of the fast Fourier transform, obtained by the corresponding X (K).)

Intuitive manipulation of a figure using key and mouse gestures(Especially useful for 3d renderings, this widget allows the user to intuitively rotate, pan and zoom any axes within a figure using key presses and mouse gestures. Additionally, press q to quit the widget, r (or double-click) to reset the current axes and escape to close the figure.)
