性能

有关提高所生成代码的性能的规范

在设计用于代码生成的 MATLAB^® 算法时，请遵循以下规范来提高生成代码的性能。

模块

在 Simulink 模型中包含 MATLAB 代码

`coder.areUnboundedVariableSizedArraysSupported`	Check if current configuration settings allow unbounded variable-size arrays (自 R2024a 起)
`coder.inline`	控制生成代码中当前函数的内联
`coder.inlineCall`	Inline called function in generated code (自 R2024a 起)
`coder.nonInlineCall`	Prevent inlining of called function in generated code (自 R2024a 起)
`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.
LAPACK Calls for Linear Algebra in a MATLAB Function Block
LAPACK function calls improve the simulation speed of MATLAB Function block algorithms that call certain linear algebra functions.
BLAS Calls for Matrix Operations in a MATLAB Function Block
BLAS function calls improve the simulation speed of MATLAB Function block algorithms that call certain low-level vector and matrix functions.
FFTW calls for fast Fourier transform functions in a MATLAB Function Block
FFTW function calls improve the simulation speed of MATLAB Function block algorithms that call MATLAB fast Fourier transform (FFT) functions.
