flopscope.accounting.polyval_cost(deg, m)[flopscope source]

Cost for polyval: Horner's method = m * deg FLOPs (FMA=1 op).

Parameters

deg:int

Argument forwarded to the analytical polyval cost formula.

m:int

Number of rows 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.
