flopscope.accounting.bartlett_cost
flopscope.accounting.bartlett_cost(n)[flopscope source]
Weighted FLOP cost of Bartlett window generation.
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.
Four ops per sample: compare, divide, add/subtract, select (single branch of numpy where-based evaluation). Weight 1.0 (no transcendental; constant in flop_cost).
