What is LU Decomposition?

LU Decomposition is a mathematical method used to factorize a square matrix into two triangular matrices: a lower triangular matrix (L) and an upper triangular matrix (U). This decomposition is widely applied in solving systems of linear equations, inverting matrices, and performing other numerical computations efficiently.

In simpler terms, LU Decomposition helps simplify complex matrix operations, making it a powerful tool in engineering, data science, and computational mathematics.

Frequently Asked Questions

What types of matrices can be decomposed using this calculator?

The calculator works with square matrices (2×2, 3×3, or 4×4). If the matrix is singular (its determinant is zero), decomposition will not be possible, and an error message will appear.

What are the limitations of LU Decomposition?

LU Decomposition is applicable only to square matrices. Additionally, singular matrices cannot be decomposed since they lack a unique solution.

Can I use this calculator for larger matrices?

Currently, the calculator supports matrices up to 4×4. For larger matrices, more advanced software or tools may be required.

What happens if I input invalid values?

The calculator validates your input and will display an error message if any values are missing or incorrect. Ensure that all input fields contain valid numbers before proceeding.
