This table summarizes what's new in Version 3.3 (R2010b):
| New Features and Changes | Version Compatibility Considerations | Fixed Bugs and Known Problems |

| Yes Details below | No | Bug
Reports Includes fixes |
New features and changes introduced in this version are:
Parameter fitting functionality now supports the following error models:
constant
proportional
combined
exponential
You can specify an error term when performing population fitting using the sbionlmefit or sbionlmefitsa function.
For more information, see Specifying an Error Model in the SimBiology documentation.
With the introduction of the PKCovariateModel object and related methods, you can now perform covariate analysis for continuous covariates.
If you use the command line, see the following section for more information:
If you use the SimBiology desktop, see the following section for more information:
SimBiology now supports multiple responses when performing a population or individual fit task.
If you use the command line, see the following sections for more information:
If you use the SimBiology desktop, see the following sections for more information:
SimBiology now supports time lags for doses used in a simulation or fit (population or individual) task.
If you use the command line, see the following sections for more information:
If you use the SimBiology desktop, see the following sections for more information:
SimBiology now supports dimensionless units when performing dimensional analysis and unit conversion. You specify dimensionless units either via the command line (by setting the ValueUnits property of a parameter object to 'dimensionless') or in the desktop (by selecting dimensionless for the ValueUnits in the Parameters pane).
The following function is updated:
sbiotrellis — Plot simulation results in trellis plot. Updated to accept multiple columns from the data set to plot on the y-axis.
After performing a parameter scan, the plot window now displays the species, parameters, and compartments associated with each subplot. Hover the mouse cursor over a subplot to display this information at the bottom of the window.

The Export tab is removed from all Model
Task panes. By default, data from these tasks automatically exports
to the MATLAB workspace. To disable data exportation, select File
> Preferences > Model Tasks, then clear the Export
task data when task completes executing check box. To export
when exporting is disabled, or to export using settings other than
the default, in the Project Explorer pane, select the Data node
under a specific Model Task, then in the Data pane,
click
to open the Export Data dialog box.
