This Python project is a command-line tool that calculates the polynomial that passes through a set of points provided by the user. The script constructs a Vandermonde matrix based on the input points and uses Cramer's rule to solve for the polynomial coefficients. It then displays the resulting polynomial in a readable format.
- Polynomial Calculation: Given a set of points, the script calculates the unique polynomial that passes through all of them.
- Interactive User Input: The user is prompted to enter the coordinates of the points, and the program interactively calculates and displays the polynomial.
- Determinant Calculation: The script uses the determinant of the matrix to calculate the polynomial coefficients, ensuring accurate results.
- Error Handling: The script includes basic error handling to ensure that inputs are valid and matrices are not singular.
- Python 3.x
- NumPy library
