coder.Function Properties

Description of MATLAB function used in code generation

coder.Function properties contain the description of a MATLAB^® function that is used in code generation. All coder.Function properties are read-only. You can use dot notation to query these properties.

You do not directly create a coder.Function object. A coder.ReportInfo object contains one coder.Function object for every MATLAB function that is used in code generation. These coder.Function objects are automatically created when you export code generation report information to a coder.ReportInfo object. For more information, see coder.ReportInfo Properties and Access Code Generation Report Information Programmatically.

Name — Name of function

character vector

This property is read-only.

Name of a MATLAB function used in code generation, specified as a character vector.

Example: 'foo'

Data Types: char

Specialization — Specialization identifier of a function

double

This property is read-only.

The specialization identifier of a MATLAB function used in code generation. A value of zero indicates that the function is not specialized. A positive value indicates that the function is specialized.

Data Types: double

File — MATLAB file containing the function

coder.CodeFile object | coder.File object

This property is read-only.

A description of the MATLAB file that contains the function used in code generation.

• If the file contains text, this property is a coder.CodeFile object. See coder.CodeFile Properties.

• If the file does not contain text (for example, a P-coded file), this property is a coder.File object. See coder.File Properties.

StartIndex — Index of the first character of the function in the text of the file

double

This property is read-only.

1-based index of the first character of the function in the text of the file. If the file does not contain text (for example, a P-coded file), this property is equal to 0.

To manually inspect the code, the line and column numbers corresponding to StartIndex are useful. Use the getLineColumn function to obtain that information.

Data Types: double

EndIndex — Index of the last character of the function in the text of the file

double

This property is read-only.

1-based index of the last character of the function in the text of the file. If the file does not contain text (for example, a P-coded file), this property is equal to 0.

To manually inspect the code, the line and column numbers corresponding to EndIndex are useful. Use the getLineColumn function to obtain that information.

Data Types: double

Variables — Variables that the function uses

array of coder.Variable objects

This property is read-only.

The array consists of one coder.Variable object for each variable the function uses, including input, output, and local variables.

Each coder.Variable object has these properties:

• Name: Name of the variable, specified as a character vector.

• Scope: Scope of the variable, specified as a character vector. Possible scope values are: 'Input', 'Output', 'Local', 'Global', 'Persistent', and 'InputOutput'.

• Type: Data type of the variable specified as a coder.Type object.

This property is applicable only in the context of the MATLAB function report of a MATLAB Function block. See Programmatically Access MATLAB Function Reports (Simulink).

Callees — MATLAB functions and methods that are called by this function

array of coder.Function objects | array of coder.Method objects

This property is read-only.

Heterogeneous array containing descriptions of MATLAB functions and methods that are called by this function. Each element of the array contains a description of one function or method.

• Array elements containing descriptions of functions are coder.Function objects.

• Array elements containing descriptions of methods are coder.Method objects. See coder.Method Properties.
