Call .NET Properties That Take an Argument

MATLAB^® represents a property that takes an argument as a method. For example, the System.String class has two properties, Chars and Length. The Chars property gets the character at a specified character position in the System.String object. For example:

str = System.String('my new string');
methods(str)

Static methods:

Compare             Intern              op_Equality         
CompareOrdinal      IsInterned          op_Inequality       
Concat              IsNullOrEmpty       
Copy                IsNullOrWhiteSpace  
Format              Join

Notice that MATLAB displays the Chars property as a method.

The Chars method has the following signature.

Return Type	Name	Arguments
char scalar RetVal	Chars	(System.String this, int32 scalar index)

To see the first character, type:

Chars(str,0)

ans =
m
