提升编译性能
用于加快大型模型编译的工作流、方法和示例
用于加快大型模型编译的优化方法包括模型编译工件的可扩展编译、增量编译和内存或磁盘缓存。
可扩展编译只需编译一次重复组件，然后会针对相同组件的其他实例重用这些编译工件，因此有助于减少由重复组件（如传输线或电池组）模式组成的模型的编译时间。可扩展编译可提升编译性能，但并不会减少模型的仿真时间。
增量编译会针对后续编译重用可重用组件的编译工件，除非在仿真运行之间修改了组件。增量编译和内存缓存可以提升同一 MATLAB® 会话中重复模型仿真和模块图更新的性能。
要利用可扩展编译和增量编译，您需要指定可重用组件并启用组件重用。内存缓存自动执行。
您可以选择将缓存的编译工件存储在磁盘上，而不是存储在内存缓存中。磁盘缓存在 MATLAB 会话之间持续存在，因此提高了给定会话中首次编译模型的性能。
