Octave User defined Function Example

Introduction

In this tutorial, we will learn about user-defined functions in Octave. User-defined functions are stored in a separate file with the filename as the function name.

User-defined function

Let’s write a sample function to convert Fahrenheit temperature to Celsius temperature.

We will use the following conversion formula:

 

\huge C = 5*(F - 32)/9

 

 function [Celsius] = FahToCel(Fahrenheit)
% Function: FahToCel.m
% 
Celsius = 5*(Fahrenheit-32)/9;
endfunction

user defined octave

Function Call

We can invoke the function with the function name and pass the parameters.

%Sample Usage
% How to invoke the user defined function
celsius = FahToCel(50);
disp(celsius);
