通过MATLAB来计算环形天线的辐射阻抗，远场方向性图，还有极坐标方向图(By MATLAB to calculate the radiation resistance of loop antennas, far-field directivity pattern, as well as polar pattern )

此为matlab详尽学习资料第十章“高级数值计算”(This is a detailed matlab learning materials Chapter 10, " Advanced numerical computing" )

完成对于图像的DCT变换反变换，FFT变换反变换，动态模糊，加噪声去噪声等等，配有图形界面，功能强大(For complete image DCT transform inverse transform, FFT transform inverse transform, as well as some dynamic blurring function, and with a graphical interface)

Compare between OFDM and SC-FDMA

说明：  这是一个基于ofdm的系统的调制解调的matlab程序(This is a ofdm modem program)

采用MATLAB仿真BPSK-OFDM的BER特性。从理论和实际两方面把输出波形作为对比。(Using MATLAB simulation of BER of BPSK-OFDM characteristics. From both theoretical and practical aspects of the output waveform as a contrast.)

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

使用matlab分析矩阵扰动对于方程求解的影响，计算矩阵的条件数！以电磁跟踪系统定位模型计算为例！(Use matlab analysis matrix perturbations equation influence calculation matrix condition number! Electromagnetic tracking system to locate model as an example!)
