setVariablePart - Set property of variable in model workspace - MATLAB (original) (raw)

Set property of variable in model workspace

Syntax

Description

[varValue](#mw%5F15abb0c4-37a3-4823-b065-bc6ab0f18074) = setVariablePart([mdlWks](#mw%5Fef1a4087-477d-4ba3-ae9e-623e41835b86),[varName.Property](#mw%5Fc3c93e65-6828-40d7-845d-12c6ddb26ced), [varValue](#mw%5F15abb0c4-37a3-4823-b065-bc6ab0f18074)) assigns varValue to the MATLAB variable propertyvarName.Property in the model workspace represented by theSimulink.ModelWorkspace object mdlWks.

Using setVariablePart is preferable to using evalin for assigning variable properties in the model workspace because thesetVariablePart function does not create a new variable or cause unintended results.

Examples

Open the example model vdp.

openExample('simulink_general/VanDerPolOscillatorExample')

Create a Simulink.ModelWorkspace object that represents the model workspace of vdp.

mdlWks = get_param('vdp','ModelWorkspace');

Create a structure named myStruct with fieldsa, b, and c.

aStruct.a = 10; aStruct.b = {1,2,3,4,5}; aStruct.c = Simulink.Parameter(7); mdlWks.assignin('myStruct',aStruct);

Assign new values to the structure fields.

setVariablePart(mdlWks,'myStruct.a', 2); setVariablePart(mdlWks,'myStruct.b{1}', 2); setVariablePart(mdlWks,'myStruct.c', Simulink.Parameter(2));

Return the new values of the structure fields. Store the values invarValuea, varValueb, andvarValuec.

varValuea = getVariablePart(mdlWks,'myStruct.a') varValueb = getVariablePart(mdlWks,'myStruct.b{1}') varValueC = getVariablePart(mdlWks,'myStruct.c.Value')

Input Arguments

collapse all

Target model workspace, specified as a Simulink.ModelWorkspace object.

Name of the target variable property, specified as a character vector.

Example: 'myVariable.Property'

Data Types: char | string

Value to assign to the value property, specified as a valid value. For example, you can specify a literal number, a structure, or an expression that evaluates to a valid value.

If you specify the name of a handle object, such as aSimulink.Parameter object, use the copy function to create a separate copy of the object.

Example: 5.12

Example: struct('a',5.12,'b',7.22)

Example: Simulink.Parameter(5.12)

Example: copy(myExistingParameterObject)

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | char | string | struct | table | cell | categorical | datetime | duration | calendarDuration | fi
Complex Number Support: Yes
