![]() For example, use the expression myParams(2).Init. Specify an expression that references a field of one of the structures To set the value of a block parameter in one of the subsystems, Suppose that you create two identical subsystems in a model.Įach structure in the array stores the three parameter values Instances of an algorithm, such as a library subsystem or a referenced This technique helps you to parameterize a model that contains multiple You can create a single variable whose value is an array of structures. To organize parameter structures that have similar characteristics, Group Multiple Parameter Structures into an Array The value of a block parameter, specify the parameter value in theīlock dialog box as the expression. To use the Offset field from the substructure SubsystemB as The single structure variable myParams containsĪll of the parameter information for the blocks in the subsystems.īecause each substructure acts as a namespace, you can define the Offset field The field whenever you change the data type of the signal. If you do not use a data type object, you must remember to change the data type of Simulink.NumericType object to set the data type of the field and the If you want theĭata type of the field to match the data type of the output signal of the block, youĬannot rely on context-sensitive data typing (see Context-Sensitive Data Typing). Suppose that you use the field to set the value of Match Field Data Type with Signal Data Type To manipulate bus objects after you create them, see Create Simulink Bus Objects and Save Simulink Bus Objects. The element Coeffs in the bus object SubsystemB. To change the dimensions of the field, modify Two-element field toĪ three-element array, the model generates an error when you set aīlock parameter value. The bus object strictly controls the field characteristics and Variables into a single structure variable: When you open the model, it creates the variables Zw, Mw,Īnd Mq in the base workspace. The example model f14 uses multiple variablesįrom the base workspace to set block parameter values. This example shows how to create and use a parameter structure To use structures to initialize bus signals, see Specify Initial Conditions for Bus Elements. Instead of passing multiple variables, you can passįor basic information about creating and manipulating MATLAB structures,įor basic information about setting block parameter values in a model, The number of individual mask parameters or model arguments that you ![]() Values to the components of a system, you can use structures to reduce If you use mask parameters or model arguments to pass parameter That each subsystem or referenced model uses. ForĮxample, use nested structures to clearly identify the parameter values Logically group sets of block parameter values. Prevents the field names from conflicting with each other and with Structure and substructure as a namespace that You must provide each field a name, but multiple structures can eachĬontain a field that uses the same name. Same scope, such as in the base workspace. You cannot create two variables that have the same name in the Reduce the number of workspace variables that youĪvoid name conflicts between workspace variables.
