flopscope.accounting.cond_cost
flopscope.accounting.cond_cost(m, n, p=None)[flopscope source]
Weighted FLOP cost of condition number.
Parameters
- m:int
Number of rows in the input matrix.
- n:int
Number of columns in the input matrix.
- p:object, optional
Argument forwarded to the analytical linalg.cond cost formula. Defaults to
None.
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.
For p=None, p=2, or p=-2, computed via SVD (cost m*n*min(m,n)).
For p=1, p=-1, p=inf, or p=-inf, computed via LU factorization
(cost ~min(m,n)^3 + m*n for norm).
