flopscope.accounting.polyfit_cost
flopscope.accounting.polyfit_cost(m, deg)[flopscope source]
Cost for polyfit: 2 * m * (deg+1)^2 FLOPs.
Parameters
- m:int
Number of rows in the input matrix.
- deg:int
Argument forwarded to the analytical polyfit cost formula.
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.
