arguments. For these function signatures, define tuples and set the repeating property

to true.

mutuallyExclusiveGroup – Definition of set of exclusive arguments

Definition of a set of sets of arguments that cannot be used together, specified as a list of

argument objects. This property is used to provide information about functions with

multiple function signatures. However, typically it is easier to define multiple function

signatures using multiple function objects. For more information, see “Multiple

Signatures” on page 30-24.

Create Function Signature File

This example describes how to create custom code suggestions and completions for a

function.

Create a function whose signature you will describe in a JSON file in later steps. The

following function accepts:

• Two required arguments


• One optional positional argument via varargin


• Two optional name-value pair arguments via varargin

myFunc is presented to demonstrate code suggestions and does not include argument

checking.

% myFunc Example function

% This function is called with any of these syntaxes:

%

% myFunc(in1, in2) accepts 2 required arguments.

% myFunc(in1, in2, in3) also accepts an optional 3rd argument.

% myFunc(___, NAME, VALUE) accepts one or more of the following name-value pair

% arguments. This syntax can be used in any of the previous syntaxes.

% * 'NAME1' with logical value

% * 'NAME2' with 'Default', 'Choice1', or 'Choice2'

function myFunc(reqA,reqB,varargin)

% Initialize default values

NV1 = true;

NV2 = 'Default';

posA = [];

if nargin > 3

if rem(nargin,2)

posA = varargin{1};

V = varargin(2:end);

else

V = varargin;

end

for n = 1:2:size(V,2)
