flopscope.accounting.slogdet_cost
flopscope.accounting.slogdet_cost(n, symmetric=False)[flopscope source]
Weighted FLOP cost of sign and log-determinant.
Parameters
- n:int
Number of columns in the input matrix.
- symmetric:bool, optional
Argument forwarded to the analytical linalg.slogdet cost formula. Defaults to
False.
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.
Simplified cubic cost model for sign and log-determinant computation.
