Code Generation for Variable Length Argument Lists - MATLAB & Simulink (original) (raw)

Main Content

When you use varargin and varargout for code generation, there are these restrictions:

• If you use varargin to define an argument to an entry-point function, the code generator produces the function with a fixed number of arguments. This fixed number of arguments is based on the number of arguments that you specify when you generate code.
• You cannot write to varargin. If you want to write to input arguments, copy the values into a local variable.
• To index into varargin and varargout, use curly braces {}, not parentheses().
• The code generator must be able to determine the value of the index intovarargin or varargout.
