Replace blocks from previous releases with latest versions
AnalysisResult = slupdate('sys', 'OperatingMode', 'Analyze')
slupdate('sys') replaces blocks in model sys from a previous release of Simulink® software with the latest versions. The slupdate function alone cannot perform all upgrade checks on your model. Use the Upgrade Advisor to access the slupdate checks and also advice and fixes for all other upgrade checks. See Model Upgrades.
Note Best practice is to first open the model, and press CTRL+D to update the model, before you call slupdate.
slupdate('sys', prompt) specifies whether to prompt you before replacing a block. If prompt equals 1, the command prompts you before replacing the block. The prompt asks whether you want to replace the block. Valid responses are
Replace the block (the default).
Do not replace the block.
Replace this and all subsequent obsolete blocks without further prompting.
If prompt equals 0, the command replaces all obsolete blocks without prompting you.
In addition to replacing obsolete blocks, slupdate
Reconnects broken links to masked blocks in libraries provided by MathWorks to ensure that the model reflects changes made to the blocks in this release. This will overwrite any custom changes you made to the masks of these blocks.
Updates obsolete configuration settings for the model.
AnalysisResult = slupdate('sys', 'OperatingMode', 'Analyze') performs only the analysis portion without updating or changing the model. This command analyzes referenced models, linked libraries, and S-functions, and then returns a data structure with the following fields:
Message — string containing a message summarizing the results
blockList — cell array listing blocks that need to be updated
blockReasons — cell array listing reasons for updating the corresponding blocks
modelList — cell array listing referenced models and the parent model
libraryList — cell array listing non-MathWorks libraries referenced
configSetList — for internal use
sfunList — cell array listing S-functions referenced
sfunOK — logical array representing S-function status, where false indicates that an S-function needs updating and true indicates otherwise
sfunType — cell array listing apparent S-function type (e.g., .mex)
