输入设定

指定 MATLAB^® 函数输入变量的属性以启用代码生成

代码生成需要设定输入类型和属性。代码生成器使用输入信息来确定在后续变量定义中应如何定义变量的类型、大小及其他属性。通过 App、命令行或使用代码生成器生成类型编辑器，使用 coder.typeof、coder.varsize 和 assert 等函数在函数代码的外部或内部来执行输入设定。对于某些输入类型，如元胞、类和全局变量，输入设定可能涉及其他考虑事项。

函数

`coder.getArgTypes`	Determine types of function input arguments by executing test file
`coder.newtype`	Create `coder.Type` object to represent type of an entry-point function input
`coder.resize`	调整 `coder.Type` 对象的大小
`coder.typeof`	Create `coder.Type` object to represent the type of an entry-point function input
`coder.varsize`	声明可变大小数据
`coderTypeEditor`	Launch the Coder Type Editor dialog （自 R2020a 起）

`coder.CellType`	Represent set of MATLAB cell arrays
`coder.ClassType`	Represent set of MATLAB classes acceptable for input specification
`coder.Constant`	Specification of constant value for code generation
`coder.EnumType`	Represent set of MATLAB enumerations acceptable for input specification
`coder.FiType`	Represent set of MATLAB fixed-point arrays acceptable for input specification
`coder.PrimitiveType`	Represent set of logical, numeric, or character arrays acceptable for input specification
`coder.StructType`	Represent set of MATLAB structure arrays acceptable for input specification
`coder.StringType`	Represent set of MATLAB strings acceptable for input specification （自 R2022b 起）
`coder.Type`	Represent set of MATLAB values acceptable for input specification
