[. . . ] Determine if enhancements, bugs, or compatibility considerations in other products impact you. If you are upgrading from a software version other than the most recent one, review the current release notes and all interim versions. For example, when you upgrade from V1. 0 to V1. 2, review the release notes for V1. 1 and V1. 2. 1 Simulink® Design OptimizationTM Release Notes What Is in the Release Notes New Features and Changes · New functionality · Changes to existing functionality Version Compatibility Considerations When a new feature or change introduces a reported incompatibility between versions, the Compatibility Considerations subsection explains the impact. Compatibility issues reported after the product release appear under Bug Reports at The MathWorksTM Web site. Bug fixes can sometimes result in incompatibilities, so review the fixed bugs in Bug Reports for any compatibility impact. Fixed Bugs and Known Problems The MathWorks offers a user-searchable Bug Reports database so you can view Bug Reports. The development team updates this database at release time and as more information becomes available. Bug Reports include provisions for any known workarounds or file replacements. Information is available for bugs existing in or fixed in Release 14SP2 or later. Information is not available for all bugs in earlier releases. Access Bug Reports using your MathWorks Account. 2 Version 1. 1. 1 (R2010a) Simulink® Design OptimizationTM Software Version 1. 1. 1 (R2010a) Simulink Design Optimization Software This table summarizes what's new in V 1. 1. 1 (R2010a): New Features and Changes No Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site Printable Release Notes: PDF Current product documentation New Engine Design and Cost Tradeoffs Demo The new Engine Design and Cost Tradeoffs demo shows how to use the Simulink® Design OptimizationTM software to optimize a design for performance and cost. 3 Simulink® Design OptimizationTM Release Notes Version 1. 1 (R2009b) Simulink Design Optimization Software This table summarizes what's new in V 1. 1 (R2009b): New Features and Changes Yes Details below Version Compatibility Considerations Yes Summary Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No New features and changes introduced in this version are: · "New Algorithm Option for fmincon (Gradient descent) and lsqnonlin (Nonlinear least squares) Methods, LargeScale (Model size) Option Removed" on page 4 · "Support for Optimization-Based Compensator Design for Plants with Delays or Specified as Frequency-Response Data" on page 6 · "Functions and Properties Being Removed" on page 6 New Algorithm Option for fmincon (Gradient descent) and lsqnonlin (Nonlinear least squares) Methods, LargeScale (Model size) Option Removed This version of the product includes changes at the command line to make the fmincon and lsqnonlin methods to be consistent with the Optimization ToolboxTM software: · Algorithm property renamed to Method. The following table summarizes values of the new Algorithm option. 4 Version 1. 1 (R2009b) Simulink® Design OptimizationTM Software Method fmincon Algorithm Values · 'active-set' (default) · 'trust-region-reflective' · 'interior-point' · 'trust-region-reflective' (default) · 'levenberg-marquardt' lsqnonlin Previously, to specify the algorithm at the command line, you set the LargeScale option to 'on' or 'off'. If you used LargeScale='on' in a previous release, use Algorithm='trust-region-reflective' instead. If you used LargeScale='off', use the following instead: · For fmincon ­ Use Algorithm='active-set'. · For lsqnonlin ­ Use Algorithm='levenberg-marquardt'. For more information about these options, see the Optimization Toolbox User's Guide. The Options dialog box includes the following updates to the Gradient descent and Nonlinear least squares methods that correspond to the command-line changes. · Algorithm option is renamed to Method. [. . . ] You can enable this option from either the GUI or at the command line. Using parallel computing can speed up the estimation time in the following situations: 8 Version 1. 0 (R2009a) Simulink® Design OptimizationTM Software · The model contains a large number of parameters to estimate. · The model is complex and takes a long time to simulate. For more information about using parallel computing for estimating model parameters, see "Speeding Up Parameter Estimation Using Parallel Computing" in the Simulink Design Optimization documentation. Updated Demos The Simulink Design Optimization demos have been categorized into the following new categories: · Parameter Estimation in Simulink · Response Optimization in Simulink · Response Optimization in SISO Design Tool · Design Optimization Using Parallel Computing · Adaptive Lookup Tables To open the Simulink Design Optimization demos, type demo simulink 'simulink design optimization' at the MATLAB prompt. Upgrading from Nonlinear Control Design Blockset Software Prior to R14, Simulink Response Optimization software was called Nonlinear Control Design Blockset software. [. . . ]
