matlab7.0应用编程，中文资料，每章一个文件(Application Programming matlab7.0, English information, each devoted to a file)

说明：  频率提取（FFT）的Matlab实现，使用该代码可在MATLAB中实现快速傅立叶变换(Frequency Extraction (FFT) of the Matlab implementation of the code in MATLAB using the fast Fourier transform in)

电流谐波分析,对电力方面的电流做谐波分析(Current harmonic analysis, the current electricity do harmonic analysis)

Prior to release 0.40, H5DUMP relied upon HDF5INFO to provide the metadata necessary, but now it now relies entirely on the low-level interface. Since it is not backwards compatible with prior releases, the old version is provided in the obsolete directory.

电磁波穿过一维介质的Matlab仿真 注意本人原创作品 不得乱传(Electromagnetic waves through Matlab simulation of one-dimensional medium)

说明：  直流电机启动模型，自己做的，可以交流作业用(dc start)

说明：  经典教材，美国人普艾克编著，非常实用的数字信号处理书(Classic textbook, edited by American Pu Yike, very practical book of digital signal processing)

MATLAB 编程问题 大家可以交流下 加油啊 好东西(MATLAB programming problem we can exchange, under)

说明：  对图像进行DWT变换后的图形结果，如上传所示！(DWT transform the image of the graphical results, as shown upload!)

说明：  首先，对复杂振动信号进行EMD分解，得到各个频率分量，接着，对各分量进行Hilbert变换，得到瞬时频率(END resolve,hilbert chang,evry imf,instantaneous frequency)
