创建系统对象

写一个matlab^®class that creates and defines a new System object™

您可以通过自定义实现方法来定义自己的系统对象。使用图形工具探索用于创建系统对象的综合API。例如，您可以插入方法以初始化，运行，重置和终止系统对象。有关定义系统对象的介绍，请参见Define Basic System Objects.

方法

`infoImpl`	Information aboutSystem object
`isdoneimpl`	End-of-data flag
`Isinactive propertyimpl`	Status of inactive property
`isTunablePropertyDataTypeMutableImpl`	设置可调属性是否可以更改数据类型
`isDiscreteStateSpecificationMutableImpl`	Control whether discrete states can change data type
`processTunedPropertiesImpl`	Action when tunable properties change
`setProperties`	Set property values using name-value pairs when creatingSystem object
`validatePropertiesImpl`	验证属性值System object
`getPropertyGroupsImpl`	Property groups for System object display

`getNumInputsimpl`	Number of inputs to the System object
`getNumOutputsimpl`	Number of outputs fromSystem object
`getNumInputs`	Number of inputs required to call theSystem object
`getNumOutputs`	Number of outputs from calling theSystem object
`isInputComplexityMutableImpl`	Set whether System object input complexity can change
`ISInputDatatyPemutableImpl`	设置系统对象输入数据类型是否可以更改
`isInputSizeMutableImpl`	设置系统对象输入大小是否可以更改
`nargin`	Number of input arguments forSystem object
`Nargout`	Number of output arguments forSystem object
`ProcessInputSpecificationChangeImpl`	Perform actions when input size, complexity, or data type change
`validateInputsImpl`	Validate inputs toSystem object

`loadObjectImpl`	LoadSystem objectfrom MAT file
`SaveObjectImpl`	节省System objectin MAT file

sysobjupdate Update customSystem objectto latest syntax

`matlab.System`	Base class for System objects
`matlab.system.mixin.FiniteSource`	Finite source mixin class

Define Basic System Objects
Create a basic System object with thestepImpl方法。

Define Property Attributes
Specify property attributes to limit the type, visibility, and value of properties.
- Validate Property and Input Values
- Set Property Values at Construction Time
- Hide Inactive Properties
- Limit Property Values to Finite List
- Process Tuned Properties
- 使用全局变量在系统对象

Change the Number of Inputs
This example shows how to set the number of inputs for a System object™ with and without usinggetNumInputsimpl.
定义复合系统对象
Define System objects that include other System objects as properties.
Handle Input Specification Changes
Implement methods to restrict when System object input complexity, data type, or size can change or implement a method to react when input specifications change.

Detailed Call Sequence

Define Finite Source Objects
This example shows how to define a System object that performs a specific number of steps or specific number of reads from a file.
节省and Load System Object
Use a MATLAB structure to save and load System object properties and state.
