通过脚本修改MATLAB的数据字典

各位可以在MATLAB命令行运行，看看每个指针的结果是什么：

myDictionaryObj = Simulink.data.dictionary.open('testDt.sldd');%获得数据字典的指针dDataSectObj = getSection(myDictionaryObj,'Design Data');%获得数据段指针fuelFlowObj = getEntry(dDataSectObj,'aaa');%获得数据指针paramObj = fuelFlowObj.getValue();%获得数据结构体指针

运行结果:

fuelFlowObj = 

  Entry with properties:

              Name: 'aaa'
Value: [1×1 Simulink.Parameter]
DataSource: 'testDt.sldd'
LastModified: '2025-Aug-07 01:23:04.828268'
LastModifiedBy: 'Administrator'
Status: 'Unchanged'

paramObj = 

  Parameter with properties:

      GenericProperty: []
DoubleProperty: 0
Int32Property: 0
LogicalProperty: 0
CharProperty: ''
OnOffCharProperty: 'off'
ColorCharProperty: 'red'
Value: 10
CoderInfo: [1×1 Simulink.CoderInfo]
Description: ''
DataType: 'auto'
Min: []
Max: []
Unit: ''
Complexity: 'real'
Dimensions: [1 1]

然后按照常规，对paramObj进行操作即可
