Steps for Gaussian Elimination
- Develop the Augmented Matrix: With an augmented matrix, the coefficient matrix and the constant vector is required to be synthesized.
- Forward Elimination: By removing the elements under the significant diagonal, the matrix must be converted into an upper triangular form.
- Back Substitution: As proceeding from the last equation and navigating upwards, we have to address the uncertainties.
Example System of Linear Equations
Let us examine the following system of equations:
2x + 3y + z = 1 \\ 4x + 4y + 2z = 2 \\ 2x + 5y + 3z = 3 \end{cases} \]
Step-by-Step Execution in MATLAB
- Form the Augmented Matrix
matlab A = [2 3 1; 4 4 2; 2 5 3];
% Coefficient matrix b = [1; 2; 3];
% Constants vector augmented Matrix = [A b]; % Augmented matrix
- Forward Elimination
matlab [n, m] = size(augmentedMatrix);
for i = 1:n-1 % Partial pivoting [~, idx] = max(abs(augmentedMatrix(i:n, i)));
idx = idx + i – 1; if idx ~= i augmentedMatrix([i idx], 🙂 = augmentedMatrix([idx i], :);
end for j = i+1:n factor = augmentedMatrix(j, i) / augmentedMatrix(i, i);
augmentedMatrix(j, i:m) = augmentedMatrix(j, i:m) – factor * augmentedMatrix(i, i:m);
end end
- Back Substitution
matlab x = zeros(n, 1);
x(n) = augmentedMatrix(n, end) / augmentedMatrix(n, n);
for i = n-1:-1:1 x(i) = (augmentedMatrix(i, end) – augmentedMatrix(i, i+1:n) * x(i+1:n)) / augmentedMatrix(i, i);
end disp(‘Solution:’);
disp(x);

Description
- Designing the Augmented Matrix: The coefficient matrix (A) and the constant vector (b) are integrated by means of augmented matrix.
- Forward Elimination: Across every row, the code repeats in an appropriate way.
To enhance numerical flexibility, carry out partial pivoting. For developing an upper triangular, we should remove the elements which are under the pivot element.
- Back Substitution: By including the previously known values from the initial row, this code addresses for each variable which initiates with the last row.
Further Concerns
- Numerical Flexibility: It is important to assure the pivot element, whether it is biggest in the Because, the problems get decreased with numerical flexibility by means of partial pivoting.
- Singular Matrices: A singular or approximately singular matrix is represented here, if a pivot element is zero or nearer to zero. A specific solution might not be carried by the system.
- Adaptability: For managing the extensive systems, the execution process can be enhanced through expanding the matrix dimensions.
