用MATLAB对图象进行放大或缩小,用双线性内差值方法.(zoom in or out the picture)

Do you still use GINPUT to graphically select points on current axes with the mouse? Try this one! With GINPUT2 you can also: 1. ZOOM: in, out (double-click)! 2. PAN: when dragging! 3. DELETE: last selected point! 4. PLOT: while selecting! (optional, just input the line style!) 5. SCALE or GEOREFERENCE images! (optional, just input: true) So, besides of selecting points in a more precise way (zooming) you can DIGITIZE(!!!) lines with the last two options, by simply using: >> ginput2(true, .k ) Enjoy it!

无线通信调制C++源代码,包含MPSK调制算法(Wireless communication modulation C++ source code, including MPSK modulation algorithm)

y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level It returns the matrix of all decompositions and the final approximations. Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes. For other wavelets, the filter values alone can be changed or WFILTERS can be used. The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author. Example: clear all t=[0:0.0003:8*pi] x=sin(5000*t)+sin(1000*t) x=x(1:2^16) level=5 Fs=1/0.003 d2wavelet(x,Fs,level) Thanks for Downloading. Don t forget to rate or comment.

本实验隶属现代数字信号处理，涉及到谱估计和谱分解，对学习数字信号的现代处理方法帮组很大。系统辨识实验实现：输入为功率为1（方差为1）的白噪声信号，通过一个线性移不变（LSI）系统，采用功率谱分析方法实现系统辨识对一个LSI系统进行辨识,并比较最后辨识出的系统与原系统的差别，分别显示出来。 (Experimental realization of system identification: input power of 1 (variance 1) of the white noise signal through a linear shift invariant (LSI) system, using power spectral analysis method of system identification of an LSI system identification, and compare the final system and identify the difference between the original system, respectively, is displayed.)
