![]() ![]() In the same way, the C code presented here eliminates x from third equation by subtracting (a3/a1) times the first equation from the third equation. It is popularly used and can be well adopted to write a program for Gauss Elimination Method in C.įor this, let us first consider the following three equations:Īssuming a1 ≠ 0, x is eliminated from the second equation by subtracting (a2/ a1) times the first equation from the second equation. This approach, combined with the back substitution, is quite general. ![]() So, this method is somewhat superior to the Gauss Jordan method. Pivoting, partial or complete, can be done in Gauss Elimination method. The C program for Gauss elimination method reduces the system to an upper triangular matrix from which the unknowns are derived by the use of backward substitution method. In Gauss-Elimination method, these equations are solved by eliminating the unknowns successively. Different analysis such as electronic circuits comprising invariant elements, a network under steady and sinusoidal condition, output of a chemical plant and finding the cost of chemical reactions in such plants require the solution of linear simultaneous equations. ![]() In engineering and science, the solution of linear simultaneous equations is very important. ![]()
