This is a code for admittance matrix formulation. Given that its inputs are bus, to bus, impedance, susceptance and tap transformer.

应用软件编程的参考书,有助于编码的规范的养成 (utility software programming reference books to help coding standard form )

Image segmentation plays an important role in computer vision and image processing applications. The motivation of this project is Image Segmentation with the presence of Intensity inhomogeneities. Intensity inhomogeneity often occurs in real world images due to spatial variations in illumination and imperfections of imaging devices
