This tool calculates the eigenvalues of a given matrix to help you with your linear algebra problems.
How to Use the Calculator
To use the eigenvalue calculator, input your matrix in the provided field in the following format:
- Separate each element in a row with a comma (,)
- Separate each row with a semicolon (;)
For example, for a 2×2 matrix with values:
1 2 3 4
You would enter:
1,2;3,4
Then, click the “Calculate” button to compute the eigenvalues of the matrix.
How it Calculates
This calculator parses the input matrix and uses numerical algorithms to find the eigenvalues. It is essential that the matrix is entered correctly, following the specified format, to obtain accurate results.
Limitations
This calculator is a simplified version and does not implement full numerical eigenvalue decomposition. For precise calculations, especially for larger matrices, specialized numerical libraries and software should be used. The example eigenvalues provided here are placeholders and not actual computations.
