Syntax

VarsOut = intersect(VarsIn1,VarsIn2)

Description

VarsOut = intersect(VarsIn1,VarsIn2) returns an array that identifies the variables described in VarsIn1 and in VarsIn2, which are arrays of Simulink.VariableUsage objects. If a variable is described by a Simulink.VariableUsage object in VarsIn1 and in VarsIn2, the function returns a Simulink.VariableUsage object that stores the variable usage information from both objects in the Users property.

intersect compares the Name, Source, and SourceType properties of the Simulink.VariableUsage objects in VarsIn1 with the same properties of the objects in VarsIn2. If VarsIn1 and VarsIn2 each contain Simulink.VariableUsage objects that have the same values for these three properties, they both describe the same variable.

To create Simulink.VariableUsage objects that describe the usage of variables in a model, use the Simulink.findVars function.

example

Examples

collapse all

Given two models, discover the variables needed by both models.

model1Vars = Simulink.findVars('model1');
model2Vars = Simulink.findVars('model2');
commonVars = intersect(model1Vars,model2Vars);

Input Arguments

collapse all

First array of variables for comparison, specified as an array of Simulink.VariableUsage objects.

Second array of variables for comparison, specified as an array of Simulink.VariableUsage objects.

Output Arguments

collapse all

Variables that are described in both input arrays, returned as an array of Simulink.VariableUsage objects. The function returns an object for each variable that is described in VarsIn1 and in VarsIn2.
