Export, Print, and Save Model Comparison Results

Step 3 of 4 in Review Changes in Simulink Models

You can save model comparison results as reports or workspace variables. If you have not yet run a comparison analysis, see Select Models to Compare.

To save your comparison results in a report, in the Comparison toolstrip, select Publish and choose the report format: HTML, Word, or PDF.

Alternatively, you can publish a comparison report to a file using the visdiff function.

If you apply filters to the comparison results, the saved report contains only filtered results.

The report also shows side by side screenshots of the modified models. Starting in R2023a, you can disable screenshots in comparison reports. Before you publish the comparison results, in the Command Window, enter these commands.

s = settings().comparisons.slx.DisplayReportScreenshots;
s.TemporaryValue = false;

To export the comparison results to the MATLAB^® base workspace, in the Comparison toolstrip, select Publish > Workspace Variable and specify the variable name.

Saving the model comparison results as a workspace variable creates an xmlcomp.Edits object in the workspace. The xmlcomp.Edits object contains information about the comparison, including file names, filters applied, and hierarchical nodes that differ between the two files.

To create an xmlcomp.Edits object at the command line without opening the Comparison Tool, enter this command.

edits = slxmlcomp.compare(modelname_A,modelname_B)

Property of `xmlcomp.Edits`	Description
`Filters`	Array of filters — Every filter has two properties, `Name` and `Value`.
`LeftFileName`	File name of left model.
`LeftRoot`	`xmlcomp.Node` object that represents the root of the left tree.
`RightFileName`	File name of right model.
`RightRoot`	`xmlcomp.Node` object that represents the root of the right tree.
`TimeSaved`	Time when results are exported to the workspace.
`Version`	MathWorks^® release-specific version number of `xmlcomp.Edits` object.

Property of `xmlcomp.Node`	Description
`Children`	Array of `xmlcomp.Node` references to child nodes, if any.
`Edited`	Boolean — If `Edited = true`, then the node is either inserted, deleted, or part of a modified matched pair.
`Name`	Name of node.
`Parameters`	Array of parameters — Every parameters has two properties, `Name` and `Value`.
`Parent`	`xmlcomp.Node` reference to parent node, if any.
`Partner`	If matched, `Partner` is an `xmlcomp.Node` reference to the matched partner node in the other tree. Otherwise, `Partner` is empty `[]`.
