Calculation method
Calculation method
Observability rank (count)
Form vertical [C;CA;...;CA^(n−1)]; Gaussian rank with supplied absolute pivot tolerance; pivot-scale ratio is diagnostic only.
State dimension (count)
Form vertical [C;CA;...;CA^(n−1)]; Gaussian rank with supplied absolute pivot tolerance; pivot-scale ratio is diagnostic only.
Gaussian pivot-scale ratio diagnostic
Form vertical [C;CA;...;CA^(n−1)]; Gaussian rank with supplied absolute pivot tolerance; pivot-scale ratio is diagnostic only.
Symbols and units

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Form vertical [C;CA;...;CA^(n−1)]; Gaussian rank with supplied absolute pivot tolerance; pivot-scale ratio is diagnostic only. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
