函数定义

用于代码加速的函数定义和调用

函数

coder.extrinsic将函数声明为外部函数,并在 MATLAB 中执行它
coder.ignoreConstPrevent use of constant value of expression for function specializations
coder.mustBeConstValidate that value is a compile-time constant (自 R2023b 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.sameSizeBinaryOpApply element-wise binary operations without implicit expansion (自 R2021b 起)
coder.noImplicitExpansionInFunctionDisable implicit expansion within the specified function in the generated code (自 R2021b 起)
coder.readRead data files at run time in generated code (自 R2023a 起)
coder.writeCreate data files that the generated code reads at run time (自 R2023a 起)
