WR2ImplicitExponentialTimeIntegration

Source: models/common/WR2ImplicitExponentialTimeIntegration.py

Define the implicit discrete exponential time integration residual of a rotation variable. The residual can be written as \(r = s - \exp\left[ (t-t_n)\dot{s}\right] \circ s_n\), where \(\circ\) denotes the rotation operator.

Inputs

variable — input · MRP · required

Integrated rotation

time — input · Scalar · default t

Time

Outputs

variable_residual — output · MRP · default variable_residual

Optional name for the derived output (defaults to ‘variable_residual’, i.e. the ‘variable’ variable name with the ‘_residual’ suffix).

Other options

rate — str

Override name for the variable rate.
