get_mass_props_unc() creates a mass properties uncertainties list from a selected row in a data frame.
Usage
get_mass_props_unc(df, id)
Arguments
- df
A data frame with (at least) these columns: id, sigma_mass,
sigma_Cx, sigma_Cy, sigma_Cz, sigma_Ixx, sigma_Iyy, sigma_Izz,
sigma_Ixy, sigma_Ixz, sigma_Iyz.
- id
The id value of the desired row.
Value
A list with the following named elements:
sigma_mass Numeric mass uncertainty.
sigma_center_mass Numeric 3-vector center of mass uncertainties.
sigma_inertia Numeric 3x3 matrix inertia tensor uncertainties.
