性能

有关提高所生成代码的性能的规范

模块

将 MATLAB 代码包含在生成可嵌入式 C 代码的模型中

`coder.inline`	控制生成的代码中特定函数的内联
`coder.unroll`	通过为每次循环迭代生成循环体的副本来展开 `for` 循环
`coder.const`	在生成的代码中将表达式折叠为常量

展开 for 循环和 parfor 循环
控制循环展开。
内联代码
内联通过用函数体替换函数调用消除了函数调用的开销。
Avoid Data Copies of Function Inputs in Generated Code
Generate code that passes input arguments by reference.
Generate Reusable Code
To reuse functions, save them in files or integrate external functions into generated code.
Control Run-Time Checks
Improve performance by disabling run-time checks.
