DCT

This a matlab program for field distribution of fiber modes.

This is the customized programmable pulse generator using matlab

说明：  这是一本关于matlab7.0的电子图书,按照它学习,很方便大家的.(This is a book about matlab7.0 e-books, according to its study, it is convenient to the people.)

1998年全国大学生数学建模竞赛A题:收益与风险 有效投资曲线

对模拟信号抽样，然后进行离散傅里叶变换，利用自编DFT函数，得到频谱，然后进行频谱的还原。(Sampling the analog signal, then the discrete Fourier transform, DFT self function obtained spectrum and the spectrum reduction.)

本程序是运用SVM来实现人脸识别算法，能直接运行且能进行二次开发(This procedure is to use SVM to implement face recognition algorithm that can run directly and can perform a secondary development)

matlab实现，验证奈奎斯特采样定理，对信号求傅里叶变换的数值解，数值求解，画出时域图，频域图(matlab implementation, verification Nyquist sampling theorem, Fourier transform of the signal find the numerical solution, numerical solution, draw the graph in time domain, frequency domain graph)

通信系统中常用到FDMA,CDMA,TDMA三种调制方式，通过这三种调制方式能产生出相应的波形。(Communication system used to FDMA, CDMA, TDMA modulation of three, by three to produce a corresponding modulation waveform.)
