Overview

In this tutorial, we will learn about Octave for Statement.
The for statement is a loop statement.

Octave for Statement

The for statement is used to execute a set of statements for a fixed number of iterations. for loop is a definite loop. We can use this loop if we know the number of iterations beforehand.

The syntax of the for statement is:

for var = expression
         for_loop_body
endfor

or

for var = expression
         for_loop_body
end

For better readability we can use the endfor to end the loop.

Simple Example

% Sample Octave Script
% For Loop Demo
% Octave Tutorials – www.TestingDocs.com

%Clear environment
clc;
clear;

% for Loop to print 1 -> 10
for n= 1 : 10
     fprintf(‘For Loop Iteration = %d \n’,n);
endfor

The for loop runs for ten iterations and prints the iteration number.

Nested for loops

In Octave, it is possible to write a nested for loop, that is, a for loop within another for loop.

For example, two nested for loops.

for i = 1:n
      for j = 1:m
     % Inner for loop statements
     end % Inner for loop
     % Some outer for loop statements
end % Outer for loop
