Defining Function In Matlab

Firstly, type this code and then save it - addTwo.m

function output = addTwo(input)

% This function will add the input with 2

output = 2 + input;

In Matlab interactive mode, type:

>> addTwo(3)

ans 5

The function also can have more than one input and output arguments. Save this code to addThen.m:

function [add,dot] = addThen(input)

% This function will add and also will multiply 

% the input arguments.

add = input + input;

dot = input * input;

Then in Matlab IDE, type

>> [a,b] = addThen(4)

a = 8

b = 16
