## LU Factorization

**1. Introduction:**

Welcome to the LU Factor a Matrix tool! This tool computes the LU factorization of a given matrix using the Doolittle algorithm. LU factorization decomposes a matrix into the product of a lower triangular matrix (L) and an upper triangular matrix (U). This decomposition is useful for solving systems of linear equations and other matrix operations.

**2. Steps to Use the Tool:**

- Enter the matrix elements in the textarea provided.
- Separate each row by a semicolon (;) and elements within each row by a comma (,).
- Click on the “Factorize LU” button.
- The tool will compute and display the L and U matrices resulting from the LU factorization.

**3. Functionality of the Tool:** This tool parses the input matrix, performs LU factorization using the Doolittle algorithm, and then displays the resulting lower triangular matrix (L) and upper triangular matrix (U).

**4. Benefits of Using This Tool:**

**Efficiency:**Quickly compute the LU factorization of a matrix without manual calculation.**Accuracy:**Avoid errors associated with manual LU factorization.**Convenience:**Accessible anytime, anywhere with an internet connection.**Versatility:**Works with matrices of any size and complexity.

**5. FAQ:**

**Q:**What is LU factorization?**A:**LU factorization decomposes a matrix into the product of a lower triangular matrix (L) and an upper triangular matrix (U).

**Q:**What is the Doolittle algorithm?**A:**The Doolittle algorithm is a method for LU factorization that uses forward substitution for L and backward substitution for U.

**Q:**Can I input non-numeric elements in the matrix?**A:**No, the tool expects numeric elements in the matrix. Non-numeric elements will result in an error.
