Calling .NET Methods

Getting Method Information

Use the following MATLAB^® functions to view the methods of a class. You can use these functions without creating an instance of the class. These functions do not list generic methods; use your product documentation to get information on generic methods.

methods — View method names
methods with '-full' option — View method names with argument list
methodsview — Graphical representation of method list

You might find the methodsview window easier to use as a reference guide because you do not need to scroll through the Command Window to find information. For example, open a methodsview window for the System.String class:

methodsview('System.String')

C# Method Access Modifiers

MATLAB maps C# keywords to MATLAB method access attributes, as shown in the following table.

C# Method Keyword	MATLAB Attribute	Example
`ref`	RHS, LHS	Call .NET Methods With ref Keyword
`out`	LHS	Call .NET Methods With out Keyword
`params`	Array of particular type	Call .NET Methods With params Keyword
`protected`, `private`, `internal`, `protected internal`	Not visible to MATLAB

VB.NET Method Access Modifiers

MATLAB maps VB.NET keywords to MATLAB method access attributes, as shown in the following table.

VB.NET Method Keyword	MATLAB Attribute
`ByRef`	LHS, RHS
`ByVal`	RHS
`Optional`	Mandatory

Reading Method Signatures

MATLAB uses the following rules to populate method signatures.

obj is the output from the constructor.
this is the object argument.
RetVal is the return type of a method.
All other arguments use the .NET metadata.

MATLAB uses the following rules to select a method signature.

Number of inputs
Input type
Number of outputs
