AN MATLAB DESIGN OF PV ARRAY

经验模态分解函数，可实现信号分解及滤波的功能。(EMD scheme which can achieve signal decomposition and noise elimanition.)

计算流体力学的网格划分，这是计算流体力学的基础(The computational fluid dynamics, this is the meshing computational fluid dynamics)

数字图像处理，MATLAB语言，RGB转HSI(Digital Image Processing, MATLAB language, RGB to HSI)

this code use for predict of electrical load.

Signals and System Want to transmit a digital image point A to point B using radio waves,

DCT基广泛应用于图像去噪，信号分离。BP与OMP算法作为贪婪算法的代表用于信号恢复。(DCT is widely used in image denoising, signal separation. As a representative of the greedy algorithm of BP and OMP algorithm for signal recovery. )

说明：  用较少的FFT点数获得对频率的精细分析，减小计算量，达到较高的分辨率(Fine analysis of spectrum)

matlab用于参数估计的代码 可以处理数据分析 方便拟合(matlab code for parameter estimation can handle data analysis)
