flopscope.accounting.cholesky_cost
flopscope.accounting.cholesky_cost(n)[flopscope source]
Weighted FLOP cost of Cholesky decomposition.
Parameters
- n:int
Number of columns in the input matrix.
Returns
- :int
Weighted public cost estimate, floored to match runtime accounting.
Notes
This helper multiplies the analytical FLOP count by the active weight from flopscope._weights and then applies int(...) so public estimates match budget deductions.
n^3/3 FLOPs (G&VL 4e Alg 4.2.1; LAPACK dpotrf).
