Java Programming Lab Code

The two or more algebraic equation are called system of equations. The Java program finds solution vector X to a system of three linear equations by matrix inverse method. a 11 x 1 + a 12 x 2 + a 13 x 3 = b 1 a 21 x 1 + a 22 x 2 + a 23 x 3 = b 2 a 31 x 1 + a 32 x 2 + a 33 x 3 = b 3 The three linear equation is represented by matrix format by separating coefficients and unknown variables | a 11 a 12 a 13 | Coefficients matrix A = | a 21 a 22 a 23 | | a 31 a 32 a 33 | unknown variable X = [ x 1 x 2 x 3 ]' non-homogeneous b = [ b 1 b 2 b 3 ]' solve given matrix A and vector b (non-homogeneous vector) find value of vector X Matrix representation A X = b ...

System of Linear Equation The two are more linear equations are called system of linear equation. ax 1 + bx 2 = b 1 cx 1 + dx 2 = b 2 System of Linear Equation in matrix representation solution of system of Linear Equation - Algorithm The following steps are carried out for solving system linear equations by inverse method. Read Matrix A 2x2 D = determinant (Matrix A) D==0, then print matrix A is singular return no solution cA = cofactor_matrix (A) Adjoint-Matrix Adj = transpose (Matrix cA) A -1 = Adj / D solution S = A -1 b print solution S Java program Solve Linear Equation The Java program LinearEquation has one constructor function and following four member functions in order t...
