addSymbol

Add data to Requirements Table block

Since R2022a

Syntax

data = addSymbol(reqTable)

data = addSymbol(reqTable,Name=Value)

Description

data = addSymbol(reqTable) adds data to the Requirements Table block, specified by reqTable.

data = addSymbol(reqTable,Name=Value) adds data by using one or more name-value arguments.

Examples

Add Data to a Requirement Table Block

Create a Requirements Table block and retrieve the RequirementsTable object.

table = slreq.modeling.create("myModel");

Add data to the block.

data = addSymbol(table);

Add Data with Specified Name, Scope, and Type Properties

Create a Requirements Table block and retrieve the RequirementsTable object.

table = slreq.modeling.create("myModel");

Add data to the block and specify the Name, Scope, and Type properties.

data = addSymbol(table,Name="u1",Scope="Output",Type="Single");

Input Arguments

reqTable — Requirements Table block

RequirementsTable object

Requirements Table block, specified as a RequirementsTable object.

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: addSymbol(table,Complexity="Off") creates data and sets the complexity of the data to Off.

Complexity — Whether data accepts complex values

"Off" (default) | "On" | "Inherited"

Whether the data accepts complex values, specified as one of these values:

Complexity	Description
"Inherited"	The data inherits complexity based on the Scope property. Input and output data inherit complexity from the Simulink® signals connected to the associated input and output ports. Local and parameter data inherit complexity from the parameter to which the data is bound.
"Off"	The data is a real number.
"On"	The data is a complex number.

Data Types: enumerated

isDesignOutput — Whether data is design model output

false or 0 (default) | true or 1

Whether the data is a design model output, specified as a numeric or logical 1 (true) or 0 (false). This property applies only when the Scope property is Input. For more information, see Treat as design model output for analysis.

Data Types: logical

Name — Name of data

"data" (default) | string scalar | character vector

Name of the data, specified as a string scalar or character vector.

Data Types: char | string

Scope — Scope of data

"Input" (default) | "Output" | "Local" | "Constant" | "Parameter"

Scope of the data that specifies where the data resides in memory relative to the block, specified as one of these values:

Scope	Description
"Input"	The data is an input signal to a Requirements Table block.
"Output"	The data is an output signal of a Requirements Table block.
"Local"	The data is defined in the current block only.
"Constant"	The data is a read-only constant value that is visible to the block.
"Parameter"	The data resides in a variable of the same name in the MATLAB® workspace, the model workspace, or in the workspace of a masked subsystem that contains this block.

Data Types: enumerated

Size — Size of data

"-1" (default) | string scalar | character vector

Size of the data, specified as a string scalar or character vector. This property must resolve to a scalar value or a MATLAB vector of values. The default value is "–1", which means that the size is inherited. For more information, see Inherit Size from Simulink (Simulink).

Data Types: char | string

Type — Data type

"Inherit: Same as Simulink" (default) | "double" | "single" | "int8" | ...

Data type, specified as:

• "Inherit: Same as Simulink"

• "double"

• "single"

• "half"

• "int64"

• "int32"

• "int16"

• "int8"

• "uint64"

• "uint32"

• "uint16"

• "uint8"

• "boolean"

• "string"

• "fixdt(1,16,0)"

• "fixdt(1,16,2^0,0)"

• "Enum: <class name>"

• "Bus: <object name>"

To modify the data type properties, use the Symbols pane and Property Inspector. For more information, see Set Data Types in Requirements Table Blocks.
