Determinant
Property
Summary
The determinant, by fraction-free elimination where the entries are polynomials
over the rationals and by Laplace expansion otherwise.
over the rationals and by Laplace expansion otherwise.
Remarks
Both are exact and neither divides in a way that could exclude a point, so the
two agree wherever both apply; which one ran is a fact about cost, not about the
answer. Laplace is optimal for a fully symbolic matrix, whose determinant
genuinely has n! terms.
