Input argument undefined - MATLAB function/subfunction You can generate code for arguments blocks that perform input argument validation in your MATLAB function. Code generation does not support repeating arguments other than varargin, name-value arguments, and output argument validation.Matlab optional input and output arguments in a function There are a few different options on how to do this. The most basic is to use varargin, and then use nargin, size etc. to determine whether the optional arguments have been passed to the function. fprintf('Total number of inputs = %d\n',nargin); nVarargs = length(varargin); fprintf('Inputs in varargin(%d):\n',nVarargs) for k = 1:nVarargs.How to Effectively Declare Functions in MATLAB with Inputs ... One common method is to allow the user to pass [] to indicate a skipped argument (that will either not be used or will get a default value). Matlab argument validation multiple classes

Name-value arguments? - matlab
One common method is to allow the user to pass [] to indicate a skipped argument (that will either not be used or will get a default value). Matlab function arguments validation
Function argument validation is a way to declare specific restrictions on function arguments. Using argument validation you can constrain the class, size, and other aspects of arguments without writing code in the body of the function to perform these tests. Input argument matlab example
For details, see Function Argument Validation. Additionally, you can check how many inputs or outputs your function receives, the names of input variables, and more.
Nargin matlab
Matlab function like a mathematical function is a rule where given a certain input or inputs, the rule tells you how to compute the output value or how to produce an effect (e.g. the plot function produces a figure). The inputs are called the “arguments” to the function. The new arguments (Output) and arguments (Output,Repeating) blocks enable you to apply argument validation to output arguments of functions and class methods. Function argument validation is a way to declare specific restrictions on function arguments. Using argument validation you can constrain the class, size, and other aspects of arguments without writing code in the body of the function to perform these tests.
Define a function in a file named calculateAverage.m that accepts an input vector, calculates the average of the values, and returns a single result. Let‘s quickly review the syntax for declaring a MATLAB function: function [out1, out2] = myFunction(in1, in2) % Function body out1 = out2 = end. We define a function name, input arguments and output arguments. This conveys: Interface: How other functions call this function.
Not enough input arguments - matlab
Define a function that accepts a variable number of input arguments using varargin. The varargin argument is a cell array that contains the function inputs, where each input is in its own cell. Define a function that returns a variable number of output arguments using varargout.
