1.	What is the Scarborough criterion?(a) The coefficient matrix has larger values in the main diagonal(b) The coefficient matrix has larger values above the main diagonal(c) The coefficient matrix has larger values below the main diagonal(d) The coefficient matrix has larger values except the main diagonalI have been asked this question by my school teacher while I was bunking the class.The question is from Discretization Aspects topic in chapter Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics
Answer» The correct option is (a) The coefficient matrix has larger values in the main diagonal For explanation I would SAY: SCARBOROUGH criterion needs the coefficient matrix to be diagonally dominant. This MEANS that the diagonal ELEMENTS should be larger than the non-diagonal elements for a particular ROW in the coefficient matrix.
