Gauss Jordan Method Pseudocode
Earlier in Gauss Jordan Method Algorithm, we discussed about an algorithm for solving systems of linear equation having n unknowns. In this tutorial we are going to develop pseudocode for this method so that it will be easy while implementing using programming language.
Pseudocode for Gauss Jordan Method
1. Start 2. Input the Augmented Coefficients Matrix (A): For i = 1 to n For j = 1 to n+1 Read Ai,j Next j Next i 3. Apply Gauss Jordan Elimination on Matrix A: For i = 1 to n If Ai,i = 0 Print "Mathematical Error!" Stop End If For j = 1 to n If i ≠ j Ratio = Aj,i/Ai,i For k = 1 to n+1 Aj,k = Aj,k - Ratio * Ai,k Next k End If Next j Next i 4. Obtaining Solution: For i = 1 to n Xi = Ai,n+1/Ai,i Next i 5. Display Solution: For i = 1 to n Print Xi Next i 6. Stop --------------- Note: All array indexes are assumed to start from 1.
