What is input and output argument in 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. Support Variable Number of Outputs. Define a function that returns a variable number of output arguments using varargout .

What is output in MATLAB?

An output function is a function that an optimization function calls at each iteration of its algorithm. You can create an output function as a function file, a local function, or a nested function. You can use the OutputFcn option with the following MATLAB® optimization functions: fminbnd.

What are input and output statements?

An input/output statement or IO statement is a portion of a program that instructs a computer how to read and process information. It pertains to gather information from an input device, or sending information to an output device.

How does the input function in MATLAB work?

The input function returns the text exactly as typed. If the input is empty, this code assigns a default value, ‘Y’ , to str. Text displayed to the user, specified as a character vector. To create a prompt that spans several lines, use ‘ ‘ to indicate each new line. To include a backslash ( ‘\\’ ) in the prompt, use ‘\\\\’.

How to create an output file in MATLAB?

Formatted Output – Examples fprintf(‘%6s%8s ‘,’index’,’value’); fprintf(‘————– ‘); n = 5; a = zeros(5,1); for( i=1:5 ) a(i) = 2*i+1; fprintf(‘%6.0f%8.1f ‘,i,a(i)); end Repeat temperature conversion example using fprintfrather than disp. Thursday, October 9, 2008 4 File Output in MATLAB Three steps: •Open the file

Which is an example of a function in MATLAB?

If you input a vector or matrix that contains a mix of numbers and character vectors, MATLAB treats every entry as a character. As an example, input the following code The software understands the input not as a 1 -by- 4 vector, but as a 1 -by- 14 character array with the value SZc14-Sep-1999.

How to declare the inputs and outputs of a function?

example function [y1,…,yN] = myfun (x1,…,xM) declares a function named myfun that accepts inputs x1,…,xM and returns outputs y1,…,yN. This declaration statement must be the first executable line of the function. Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores.
