Assignment: Matrix Algebra for Homogeneous & Non-Homogeneous Linear Algebraic System
Assignment QuestionThe following linear algebraic equations, represents the 4 dof lake system, where RHS vector consists of the mass loading rate of chloride to each of the 4 lakes and , , and the resulting chloride concentrations for Lakes Powell, Mead, Mohave, and Havasu, respectively.
a. If the volumetric flow rates are given as follow: , , and . Use determinant analysis to check the condition of the system, then predict the characteristic of the solution without calculation.
(1 mark)
b. Solve the concentrations in each of the four lakes by using GEwPP method. The calculation must involve the scaling, partial pivoting, forward elimination and the backward substitution procedures.
(2 mark)
c. Discuss the advantage of GEwPP method and disadvantage of Cramer’s rule in terms of efficiency and accuracy for solving high dimension inverse problem with singular matrix.
