## What is Matlab Narginchk?

narginchk( minArgs , maxArgs ) validates the number of input arguments in the call to the currently executing function. narginchk throws an error if the number of inputs specified in the call is fewer than minArgs or greater than maxArgs .

### How do you find the number of input parameters in Matlab?

Use nargin in the body of the function to determine the number of inputs. At the command prompt, call the addme function with two inputs.

**How do you validate input in MATLAB?**

Use function argument validation in MATLABĀ® to declare specific restrictions on function input arguments. You can constrain the class, size, and other aspects of function input values without writing code in the body of the function to perform these tests.

**How many outputs can a function have MATLAB?**

You cannot pass more than one (1) argument out of a function that is used in the MATLAB FCN block. If you need to pass more than one variable out of a function, you will have to concatenate all variables into one vector, and pass that vector out of the function.

## What are input arguments in MATLAB?

Support Variable Number of Inputs 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.

### What is a flag in MATLAB?

Introduction to Matlab Flag. Flag is a variable that we use as an indication or a signal to inform our program that a specific condition is met; mostly it is a Boolean variable (taking two values: True or False).

**How do you check if a character is valid in MATLAB?**

matchedStr = validatestring( str , validStrings ) checks the validity of str against validStrings . The text is valid if it is an unambiguous, case-insensitive match to any element in validStrings . The validatestring function supports partial matching of leading characters.

**Can a function have 2 inputs?**

Short answer: Yes. Long answer: Yes, but using the Cartesian product, you can consider multiple inputs as being a single input, where the single input is an ordered pair.

## Can two inputs have the same output?

By definition, the inputs in a function have only one output. The input 1 has two outputs: 0 and 5. The relation is not a function….

(Input) Family Member’s name | (Output) Family Member’s Age |

Nellie | 13 |

Marcos | 11 |

Samuel | 47 |

### How many outputs can a function have Matlab?

**What is Exitflag?**

An exit flag is an integer that is a code for the reason the solver halted its iterations. In general: Positive exit flags correspond to successful outcomes. Negative exit flags correspond to unsuccessful outcomes.

**In which case would you use Varargin in a function you write in MATLAB?**

Direct link to this answer

- varargin is used when the number of input parameter might change. Basically, it puts all input arguments into a cell array. The number of input parameters is given by.
- You can access any of the input values inside the function by.
- where ind is the index number of your argument.

## How do you know if a variable is valid?

A valid variable name begins with a letter and contains not more than namelengthmax characters. Valid variable names can include letters, digits, and underscores. MATLAB keywords are not valid variable names.
