- 'on' — Return a linearized model that does not include states from noncontributing
linearization paths. - 'off' — Return a linearized model that includes all the states of the model.
Dead linearization paths can include:
- Blocks that linearize to zero.
- Switch blocks that are not active along the path.
- Disabled subsystems.
- Signals marked as open-loop linearization points.
For example, if this flag set to 'on', the linearization result of the model shown in the
following figure includes only two states. It does not include states from the two blocks
outside the linearization path. These states do not appear because these blocks are on a
dead linearization path with a block that linearizes to zero (the zero gain block).
This option applies only when LinearizationAlgorithm is 'blockbyblock'.
BlockReduction is always treated as 'on' when LinearizationAlgorithm is
'numericalpert' or 'numericalpert2'.
IgnoreDiscreteStates — Flag indicating whether to remove discrete-time
states
'off' (default) | 'on'
Flag indicating whether to remove discrete-time states from the linearization, specified as
the comma-separated pair consisting of 'IgnoreDiscreteStates' and one of the
following:
- 'off' — Always include discrete-time states.
