Solving simultaneous equations using matrix functions in …

educ.jmu.edu

When solving simultaneous equations, we can use these functions to solve for the unknown values. For example, if you are faced with the following system of equations: a + 2b + 3c = 1 a –c = 0 2a + b = 1.25 Using matrix Algebra, [] [] [] To solve for the vector [], we bring the first matrix over to the right-hand side by dividing both sides by

1. Writing simultaneous equations in matrix form Consider the simultaneous equations x+2y = 4 3x− 5y = 1 Provided you understand how matrices are multiplied together you will realise that these can be written in matrix form as 1 2 3 −5! x y! = 4 1! Writing A = 1 2 3 −5!, X = x y!, and B = 4 1! we have AX = B This is the matrix form of the ...

16.810 (16.682) 6 What is the FEM? Description-FEM cuts a structure into several elements (pieces of the structure).-Then reconnects elements at “nodes” as if nodes were pins or drops of glue that hold elements together.-This process results in a set of simultaneous algebraic equations.FEM: Method for numerical solution of field problems. Number of degrees-of-freedom (DOF)
