Condition Number Calculator for Matrix Analysis

The condition number κ(A) for a matrix A is defined as the product of the matrix norm of A and the matrix norm of its inverse: κ(A) = ||A|| ⋅ ||A^-1||.
Where:

• A = The input matrix.
• A^-1 = The inverse of matrix A.
• || ⋅ || = A consistent matrix norm (e.g., 1-norm, ∞-norm, 2-norm/spectral norm).

For this calculator, specifically for a 2x2 matrix, we use the infinity norm (maximum absolute row sum norm) for calculation.
