事件函数

自定义默认模型初始化和终止方法

通过向默认模型初始化和终止方法中添加自定义例程，对动态启动和关闭行为进行建模。在仿真过程中，用事件控制方法何时执行。创建用初始值重新初始化模块的函数。

模块

自定义例程

Initialize Function	在发生模型初始化事件时执行子系统
Reinitialize Function	Execute subsystem on model or subsystem reinitialize event (自 R2022a 起)
Reset Function	在发生模型重置事件时执行子系统
Terminate Function	在发生模型终止事件时执行子系统

读取器和写入器

State Reader	Read a block state
State Writer	Write to a block state
Parameter Writer	Write to block parameter or variable
Data Store Read	从数据存储中读取数据
Data Store Write	向数据存储中写入数据

模型设置

Parameter Writer 模块验证

Globally or locally enable parameter validation (自 R2023a 起)
