## Check if Matrix is Singular

**1. Introduction:**

Welcome to the Check if a Matrix is Singular Tool! This tool helps you determine whether a given matrix is singular or not. Whether you're studying linear algebra or working with matrices in your field, this tool provides a quick way to analyze the singularity of a matrix.

**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 "Check Singular" button.
- The tool will determine if the matrix is singular or not and display the result.

**3. Functionality of the Tool:** This tool parses the input matrix, calculates its determinant using the recursive method, and checks if the determinant is zero. If the determinant is zero, the matrix is singular; otherwise, it's not singular.

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

**Efficiency:**Quickly determine the singularity of a matrix without manual calculation.**Accuracy:**Avoid errors associated with manual determinant calculation.**Convenience:**Accessible anytime, anywhere with an internet connection.**Educational:**Great for learning about matrix singularity and determinant calculation.**Versatility:**Works with matrices of any size and complexity.

**5. FAQ:**

**Q:**How should I format the input matrix?**A:**Separate each row by a semicolon (;) and elements within each row by a comma (,). For example, "1,2,3;4,5,6;7,8,9" represents a 3x3 matrix.

**Q:**What if I input an invalid matrix?**A:**If the input matrix is invalid (e.g., incorrect formatting or non-numeric elements), the tool will prompt you to enter a valid matrix.

**Q:**What does it mean if the matrix is singular?**A:**A singular matrix has a determinant of zero, indicating that it is not invertible and its columns are linearly dependent.
