This table summarizes what's new in V 1.2 (R2010b):
| New Features and Changes | Version Compatibility Considerations | Fixed Bugs and Known Problems |
|---|---|---|
| Yes Details below | Yes Summary | Bug
Reports Includes fixes |
New features and changes introduced in this version are:
You can now estimate the initial states of:
Model references
SimHydraulics® blocks
SimMechanics™ blocks
SimPowerSystems™ blocks
Simscape™ blocks
You can perform initial state estimation either using the GUI or from the command-line interface. For more information, see:
Previously, you represented the states of an Integrator block having multiple state names by using one StateData or State object. Now, each state name requires one StateData or State object. Therefore, estimating the states of such an Integrator block errors. Instead, create a TransientExperiment or Estimation object to automatically create StateData and State objects, respectively.
Previously, the Domain property of the State Data and State objects was used to track SimMechanics and SimPowerSystems blocks with states. This property is no longer required and has been removed.
| Function or Function Element Name | What Happens When you Use the Function or Element? | Use This Instead | Compatibility Considerations |
