typedef CartPoleParamsIndices K |
An abbreviation for our row index constants.
CartPoleParams | ( | ) |
Default constructor.
Sets all rows to their default value:
mc
defaults to 10.0 kg. mp
defaults to 1.0 kg. l
defaults to 0.5 m. gravity
defaults to 9.81 m/s^2. CartPoleParams | ( | const CartPoleParams< T > & | other | ) |
|
noexcept |
|
finalvirtual |
Returns a new BasicVector containing a copy of the entire vector.
Caller must take ownership, and may rely on the NVI wrapper to initialize the clone elementwise.
Subclasses of BasicVector must override DoClone to return their covariant type.
Reimplemented from BasicVector< T >.

finalvirtual |
Get the bounds for the elements.
If lower and upper are both empty size vectors, then there are no bounds. Otherwise, the bounds are (*lower)(i) <= GetAtIndex(i) <= (*upper)(i) The default output is no bounds.
Reimplemented from VectorBase< T >.
