matlab_image

matlab 图像处理命令，对matlab初学者很有帮助。(matlab image processing orders, for matlab beginners helpful.)

采用matlab语言编写的数值模拟用网格的生成，网格的细化加密(Using matlab language of the numerical simulation of the grid generation, grid refinement Encryption)

matlab 采用OTSU方法实现灰度图像二值化(OTSU method using gray image binarization)

在matlab上将图像从空间域变换到频率域，主要包括Radon变换和反变换、傅里叶变换和反变换、离散余弦变换和反变换等(In matlab image will be transformed the spatial domain to the frequency domain, including the Radon transform and inverse transform, Fourier transform and inverse transform, the discrete cosine transform and inverse transform)

一份基于simulink很实用的EKF估计soc程序.(A very practical simulink based EKF estimate soc program.)

wavelet transform matlab code

说明：  对ask调制解调过程进行了matlab仿真，程序完整！(Ask modulation and demodulation process of a matlab simulation of a complete program!)

求出多个信号的FFT频率并显示谱图，同时求出多个信号的功率谱并显示谱图(The FFT frequency of multiple signal and display the spectrum diagram, at the same time, the power spectrum of multiple signal and display spectrogram )

System will automatically delete the directory of debug and release, so please do not put files on these two directory.

说明：  本程序实现了短数据序列不同窗函数的welch功率谱估计，然后又求了他们的平均标准差，从而判断各个窗函数的优劣。只要稍作修改就能实现不同信噪比下的功率估计，同时也可以实现长数据序列的估计。(This procedure has a short data series of different welch window function power spectrum estimation, and then seek their average standard deviation, and thus to determine the merits and demerits of each window function. As long as we can with some slight modifications under different signal to noise ratio power estimate, but also the realization of a long data sequence can be estimated.)
