What Makes a Determinant Calculator 'Accurate'?
When discussing the 'most accurate' determinant calculator, it's important to understand that for standard matrices, any correctly implemented algorithm will yield the mathematically correct determinant. The 'accuracy' often refers more to: 1. Precision: How floating-point numbers are handled, especially for very large matrices where tiny errors can accumulate. 2. Symbolic vs. Numeric: Whether it can provide an exact symbolic answer (e.g., in terms of variables) or only a numerical approximation. 3. Robustness: How well it handles edge cases, ill-conditioned matrices, or very large dimensions. The top tools are those that are widely trusted, highly optimized, and offer a range of capabilities beyond just determinants.
