以编程方式控制 Scope 模块
此示例说明如何使用编程脚本控制示波器。
使用 Simulink 配置对象
使用示波器配置对象以编程方式访问示波器参数。
修改标题、轴标签和轴范围
打开或关闭图例或网格
控制输入数目
更改显示画面的数量以及哪个显示画面处于活动状态
创建一个模型并添加 Scope 和 Time Scope 模块。然后，使用 get_param 创建示波器配置对象 myConfiguration。
mdl = 'myModel'; new_system(mdl); add_block('simulink/Sinks/Scope', [mdl '/myScope']); add_block('dspsnks4/Time Scope', [mdl '/myTimeScope']); myConfiguration = get_param([mdl '/myScope'],'ScopeConfiguration')
myConfiguration =

设置属性。
myConfiguration.DataLoggingMaxPoints ='10000';查找 Scope 和 Time Scope 模块。
find_system(mdl,'LookUnderMasks','on','IncludeCommented','on', ... 'AllBlocks','on','BlockType','Scope')
ans = 2×1 cell
{'myModel/myScope' }
{'myModel/myTimeScope'}
仅查找 Simulink Scope 模块。
find_system(mdl,'LookUnderMasks','on','IncludeCommented','on',... 'AllBlocks','on','BlockType','Scope','DefaultConfigurationName',... 'Simulink.scopes.TimeScopeBlockCfg')
ans = 1×1 cell array
{'myModel/myScope'}
仅查找 DSP Time Scope 模块。
find_system(mdl,'LookUnderMasks','on','IncludeCommented','on',... 'AllBlocks','on','BlockType','Scope','DefaultConfigurationName',... 'spbscopes.TimeScopeBlockCfg')
ans = 1×1 cell array
{'myModel/myTimeScope'}
