GM(1,1)灰色预测,作为例子，可以很好地掌握灰色预测最基本的东西，希望对大家有用(GM (1,1) gray prediction, as an example, can be a good grasp of the most basic things gray forecast, we hope to be useful)

Simulation model of solar energy system used in modelling of renewable hybrid energy power system

说明：  用FCM算法实现了图像分割，效果较好，可以更改聚类数目(FCM algorithm is used to realize image segmentation. The result is good, and the number of clusters can be changed)

模拟2个独立窄带信号入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵列的阵元数为10，快拍数为200。阵元间距为入射信号波长的1／2，信噪比为20dB，信号入射角度差分别为5°，10°，20°。(Simulate two independent narrowband signals incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the number of array elements of the array is 10, the number of snapshots to 200. Element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB, the signal difference between the angle of incidence was 5 °, 10 °, 20 °.)
