Matlab varargin

Help Center Help Center. Specify varargin by using lowercase characters. After any explicitly declared inputs, include varargin as the last input argument. When the function executes, varargin is a 1-by- N cell array, where N is the number of inputs that the function receives after the explicitly declared inputs. If the function receives no inputs after the explicitly declared inputs, then varargin is an empty cell array. Define a function in a file named acceptVariableNumInputs. Define a function in a file named definedAndVariableNumInputs. Define a function in a file named variableNumInputAndOutput. The number of arguments that you specify when you generate code determines the fixed number of arguments. You cannot write to varargin. If you want to write to input arguments, first copy the input arguments into a local variable. The index into varargin must be a compile-time constant. You can create cell arrays through only the use of varargin. You cannot multi-index into cell arrays. For example, this code snippet causes an error in HDL code generation.
